We believe there are several key growth trends shaping the wireless industry. First is the advent of the mobile Internet, where consumers are increasingly demanding mobile devices with faster data rates, advanced image quality and improved Web connections. We believe this demand is one of the biggest secular growth trends in technology.

On the high-end of the cellular handset market, the smart phone growth —- which is at the heart of the mobile Internet phenomenon —- is fostering this industry wide sea change. In effect, the smart phone is moving from a higher end tool reserved for the corporate executive to an increasingly mainstream communication platform necessity —- one that is changing the way in which we live, work and play. Social networking sites such as Facebook and Twitter are only fueling this trend. Furthermore, this segment is being embraced and widely promoted by carriers who benefit from the highly profitable data services revenue stream as subscribers move to enhanced data plans.

Another trend in the wireless industry is the convergenceThe increased presence of multimedia-rich mobile devices and the recognition ofhas led manufacturers to recognize the increasingly important role multimode Front-End Modules (“FEM”) play in the rapidly evolving wireless handset market, particularly as the industry migrates to 3G and 4G technologies which enable applications such as Web browsing, video streaming, gaming, MP3 players and cameras. Next-generation EDGE, WEDGE and WCDMA wireless platforms are becomingnow being used in the majority of the more than one billion cellular phones the industry produces annually. With this accelerating trend, theannually which results in increasing complexity in the FEM increases asbecause each new wireless platform and operating frequency band requires additional amplifier, filtering and switching content to support:

Further, given constraints on handset size and power consumption, these complex modulesFEMs must remain physically small, energy efficient and cost effective, while also managing an unprecedented level of potential signal interference within the handset.

Our customer engagements are increasingly centered on solving highly complex multimode, multiband, switching, filtering, digital control and amplification challenges — system-level requirements which intersect with Skyworks’ core competencies. Skyworks continues to invest in developing architectures which optimize power efficiency while minimizing cost and footprint, allowingwhich we believe will allow us to meet our customers’ demanding next-generation technology requirements as well as stringent quality standards and manufacturing scale necessities.

As the industry migrates to multi-mode EDGE, WEDGE, WCDMA and LTE architectures across a multitude of wireless broadband applications, RF complexity in the transmit and receive chain substantially increases given simultaneous voice and high speed data communications requirements, coupled with the need for backward compatibility to existing networks. As a result of this complexity in the front-end module,FEM, we believe that our addressable market is increasing significantly.

Our product portfolio consists of:

We believe we possess a broad technology capabilitycapabilities and one of the most complete wireless communications product portfolios in the industry.

By turning complexity into simplicity, we provide our customers with the following competitive advantages:

Our products are primarily sold through a direct Skyworks sales force. This team is globally deployed across all of our major market regions. In some markets we supplement our direct sales effort with independent manufacturers’ representatives, assuring broader coverage of territories and customers. We also utilize distribution partners, some of which are franchised globally with others focused in specific regional markets (e.g., Europe, North America, China and Taiwan).

We maintain an internal marketing organization that is responsible for developing sales and advertising literature, print media, such as product announcements and catalogs, as well as a variety of Web-based content. Skyworks’ sales engagement begins at the earliest stages in a customer design. We strive to provide close technical collaboration with our customers at the inception of new programs. This relationship allows our team to facilitate customer-driven solutions, which leverage the unique strength of our product portfolio while providing high value and greatly reducing time-to-market.

We believe that the technical and complex nature of our products and markets demand an extraordinary commitment to maintain intimate ongoing relationships with our customers. As such, we strive to expand the scope of our customer relationship to include design, engineering, manufacturing, purchasing and project management. We also employ a collaborative approach in developing these relationships by combining the support of our design teams, applications engineers, manufacturing personnel, sales and marketing staff and senior management.

For information regarding customer concentration and revenues from external customers, for each of the last three fiscal years, see Note 18 of Item 8 of this Annual Report on Form 10-K.

We own and are licensed under numerous United States and foreign patents and patent applications related to our products, our manufacturing operations and processes, and other activities. In addition, we own a number of trademarks and service marks applicable to certain of our products and services. We believe that intellectual property, including patents, patent applications, trade secrets and trademarks are of material importance to our business. We rely on patent, copyright, trademark, trade secret and other intellectual property laws, as well as nondisclosure and confidentiality agreements and other methods, to protect our confidential and proprietary technologies, devices, algorithms and processes. We cannot guarantee that these efforts will meaningfully protect our intellectual property, and others may independently develop substantially equivalent proprietary technologies, devices, algorithms or processes. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and effective copyright, patent, trademark and trade secret protection may not be available in those jurisdictions. In addition to protecting our proprietary technologies and processes, we strive to strengthen our intellectual property portfolio to enhance our ability to obtain cross-licenses of intellectual property from others, to obtain access to intellectual property we do not possess and to more favorably resolve potential intellectual property claims against us. Furthermore we seek to generate high gross margin revenue through the sale and license of non-core intellectual property and occasionally purchase intellectual property to support our core business. Due to rapid technological changes in the industry, we believe that establishing and maintaining a technological leadership position depends primarily on our ability to develop new innovative products through the technical competence of our engineering personnel.

We compete on the basis of time-to-market, new product innovation, overall product quality and performance, price, compliance with industry standards, strategic relationships with customers and baseband vendors, and protection of our intellectual property. Certain competitors may be able to adapt more quickly than we can to new or emerging technologies and changes in customer requirements, or may be able to devote greater resources to the development, promotion and sale of their products than we can.

Our products and markets are subject to continued technological advances. Recognizing the importance of such technological advances, we maintain a high level of research and development activities. We maintain close collaborative relationships with many of our customers to help identify market demands and target our development efforts to meet those demands. We are focusingfocus our development efforts on new products, design tools and manufacturing processes usingleveraging our core technologies. Our research and development expenditures for fiscal years ended October 2, 2009, October 3, 2008, and September 28, 2007 were $124.0 million, $146.0 million, and $126.1 million, respectively. The reduction in research and development expenditures between fiscal year 2008 and fiscal year 2009 was principally the result of the exit of non-core product areas in the second quarter of fiscal 2009.

Raw materials for our products and manufacturing processes are generally available from several sources. It is our policy not to depend on a sole source of supply unless market or other conditions dictate otherwise. Consequently,

Our sales are made primarily pursuant to standard purchase orders for delivery of products, with such purchase orders officially acknowledged by us according to our own terms and conditions. We also maintain Skyworks-owned finished goods inventory at certain customer “hub” locations. We do not recognize revenue until these customers consume the Skyworks-owned inventory from these hub locations. Due to industry practice, which allows customers to cancel orders with limited advance notice to us prior to shipment, and with little or no penalty, we believe that backlog as of any particular date may not be a reliable indicator of our future revenue levels. The cancellation or deferral of product orders, the return of previously sold products, or overproduction due to a change in anticipated order volumes could result in us holding excess or obsolete inventory, which could result in inventory write-downs and, in turn, could have a material adverse effect on our financial condition.

Federal, state and local requirements relating to the discharge of substances into the environment, the disposal of hazardous wastes, and other activities affecting the environment have had, and will continue to have, an impact on our manufacturing operations. Most of our customers have mandated that our products comply with local and regional lead free and other “green” initiatives. We believe that our current expenditures for environmental capital investment and remediation necessary to comply with present regulations governing environmental protection, and other expenditures for the resolution of environmental claims, will not have a material adverse effect on our liquidity and capital resources, competitive position or financial condition. We cannotare unable to assess the possible effect of compliance with future requirements.

Sales of our products are subject to seasonal fluctuation and periods of increased demand in end-user consumer applications, such as cellular handsets. The highest demand for our handset products generally occurs in the calendar quarter ending in December. The lowest demand for our handset products generally occurs in the calendar quarter ending in March.

For information regarding net revenues by geographic region for each of the last three fiscal years, see Note 18 of Item 8 of this Annual Report on Form 10-K. The majority of our tangible long lived assets are located in the United States of America and Mexico (see Note 18 of Item 8). Risks attendant to our foreign operations are discussed in Item 1A-Risk Factors.

As of October 2, 2009,1, 2010, we employed approximately 3,3003,700 persons. Approximately 400450 of our employees in Mexico are covered by collective bargaining agreements.

You should carefully consider the risks described below in addition to the other information contained in this report, before making an investment decision. Our business, financial condition or results of operations could be harmed by any of these risks. The risks and uncertainties described below are not the only ones we face. Additional risks not currently known to us or other factors not perceived by us to present significant risks to our business at this time also may impair our business operations, financial condition or results from operations.

Although we believe that the market for wireless communications semiconductor products has stabilized, continued uncertainty and economic weakness could further contractresult in another market contraction and, as a result, our business, financial condition and results of operations for our current fiscal year would likely be materially and adversely affected. Such periods of industry downturn are characterized by diminished product demand and revenues, manufacturing overcapacity, excess inventory levels, and accelerated erosion of average selling prices.prices, and restructuring and/or impairment charges. Furthermore, downturns in the wireless communications semiconductor industry may be prolonged, and any extended delay or failure of the wireless semiconductor market to recover from an economic downturn would materially and adversely affect our business, financial condition and results of operations beyond our current fiscal year.

Our revenues, earnings and other operating results have fluctuated substantiallysignificantly on a quarterly and annual basis in the pastprior fiscal years and our revenues, earnings and other operating results may fluctuate in the future. These fluctuations are due to a number of factors, many of which are beyond our control.

These factors include, among others:

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially and adversely affect our quarterly or annual operating results. If our operating results fail to meet the expectations of analysts or investors, it could materially and adversely affect the price of our common stock.

Public stock markets have recently experienced extreme price and trading volume volatility. This volatility has significantly and negatively affected the market prices of securities of many technology companies, including the market price of our common stock. Thesestock in late 2008 and early 2009. The return of such volatility could result in broad market fluctuations may furtherthat could materially and adversely affect the market price of our common stock in future periods.

In addition, fluctuations in our stock price, volume of shares traded, and changes in our trading multiples may make our stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stocks rapidly, exacerbating price fluctuations in either direction. Our company has been, and in the future may be, the subject of commentary by financial news media. Such commentary may contribute to volatility in our stock price. If our operating results do not meet the expectations of securities analysts, the financial news media or investors, our stock price may decline, possibly substantially over a short period of time.

The wireless communications semiconductor industry in general and the markets in which we compete in particular are very competitive. We compete with U.S.United States and international semiconductor manufacturers of all sizes in terms of resources and market share, including Avago Technologies, RF Micro Devices and Avago.Triquint Semiconductor.

We currently face significant competition in our markets and expect that intense price and product competition will continue. This competition has resulted in, and is expected to continue to result in, declining average selling prices for our products and increased challenges in maintaining or increasing market share. Furthermore, additional competitors may enter our markets as a result of growth opportunities in communications electronics, the trend toward global expansion by foreign and domestic competitors and technological and public policy changes. We believe that the principal competitive factors for semiconductor suppliers in our markets include, among others:

We might not be able to successfully address these factors. Many of our competitors enjoy the benefit of:

As a result, certain competitors may be able to adapt more quickly than we can to new or emerging technologies and changes in customer requirements or may be able to devote greater resources to the development, promotion and sale of their products than we can.

Current and potential competitors have established, or may in the future establish, financial or strategic relationships among themselves or with customers, resellers or other third parties. These relationships may affect customers’ purchasing decisions. Accordingly, it is possible that new competitors or alliances among competitors could emerge and rapidly acquire significant market share. We may not be able to compete successfully against current and potential competitors. Increased competition could result in pricing pressures, decreased gross margins and loss of market share and may materially and adversely affect our business, financial condition and results of operations.

The wireless communications semiconductor industry generally and, in particular, the markets into which we sell our products are highly cyclical and characterized by constant and rapid technological change, continuous product evolution, price erosion, evolving technical standards, short product life cycles, increasing demand for higher levels of integration, increased miniaturization, reduced power consumption and wide fluctuations in product supply and demand. Our operating results depend largely on our ability to continue to cost-effectively introduce new and enhanced products on a timely basis. The successful development and commercialization of semiconductor devices and modules is highly complex and depends on numerous factors, including:

We will be required to continually evaluate expenditures for planned product development and to choose among alternative technologies based on our expectations of future market growth. We may not be able to develop and introduce new or enhanced wireless communications semiconductor products in a timely and cost-effective manner, and our products may not satisfy customer requirements or achieve market acceptance or we may not be able to anticipate new industry standards and technological changes. We also may not be able to respond successfully to new product announcements and introductions by competitors or to changes in the design or specifications of complementary products of third parties with which our products interface. If we fail to rapidly and cost-effectively introduce new and enhanced products in sufficient quantities that meet our customers’ requirements, our business and results of operations would be materially and adversely harmed.

In addition, prices of many of our products decline, sometimes significantly, over time. Our products may become obsolete earlier than planned or may not have life cycles long enough to allow us to recoup the cost of our investment in designing such products. Accordingly, we believe that to remain competitive, we must continue to reduce the cost of producing and delivering existing products at the same time that we develop and introduce new or enhanced products. We may not be able to continue to reduce the cost of our products to remain competitive.

Our products are not sold directly to the end-user, but are components or subsystems of other products. As a result, we rely on OEMs and ODMs of wireless communications electronics products to select our products from among alternative offerings to be designed into their equipment. Without these “design wins,” we would have difficulty selling our products. If a manufacturer designs another supplier’s product into one of its product platforms, it is more difficult for us to achieve future design wins with that platform because changing suppliers involves significant cost, time, effort and risk on the part of that manufacturer. Also, achieving a design win with a customer does not ensure that we will receive significant revenues from that customer. Even after a design win, the customer is not obligated to purchase our products and can choose at any time to reduce or cease use of our products, for example, if its own products are not commercially successful, or for any other reason. We may not continue to achieve design wins or to convert design wins into actual sales, and failure to do so could materially and adversely affect our operating results.

Our manufacturing operations are complex and subject to disruption, including due to causes beyond our control. The fabrication of integrated circuits is an extremely complex and precise process consisting of hundreds of separate steps. It requires production in a highly controlled, clean environment. Minor impurities, contamination of the clean room environment, errors in any step of the fabrication process, defects in the masks used to print circuits on a wafer, defects in equipment or materials, human error, or a number of other factors can cause a substantial percentage of wafers to be rejected or numerous die on each wafer to malfunction. Because our operating results are highly dependent upon our ability to produce integrated circuits at acceptable manufacturing yields, these factors could have a material adverse affect on our business. In addition, although we invest significant resources in the testing of our products, we may discover from time to time defects in our products after they have been shipped, and we may be required to incur additional development and remediation costs, pursuant to warranty and indemnification provisions in our customer contracts and purchase orders. The potential liabilities associated with these, and similar, provisions in certain of our customer contracts are capped at significant amounts, or are uncapped. These problems may divert our technical and other resources from other product development efforts and could result in claims against us by our customers or others, including liability for costs associated with product

earthquake, flooding, war, acts of terrorism, health advisories or risks, or other natural or manmade disasters, as well as equipment maintenance, repairs and/or upgrades such as the conversion to a 6” wafer manufacturing line currently in process at our Newbury Park, California facility.upgrades. Disruptions of our manufacturing operations could cause significant delays in shipments until we are able to shift the products from an affected facility or subcontractor to another facility or subcontractor. In the event of such delays, the required alternative capacity, particularly wafer production capacity, may not be available on a timely basis or at all. Even if alternative wafer production or assembly and test capacity is available, we may not be able to obtain it on favorable terms, which could result in higher costs and/or a loss of customers. We may be unable to obtain sufficient manufacturing capacity to meet demand, either at our own facilities or through external manufacturing or similar arrangements with others.

Due to the highly specialized nature of the gallium arsenide integrated circuit manufacturing process, in the event of a disruption at the Newbury Park, California or Woburn, Massachusetts semiconductor wafer fabrication facilities for any reason, alternative gallium arsenide production capacity would not be immediately available from third-party sources. These disruptions could have a material adverse effect on our business, financial condition and results of operations.

Minor deviations or perturbations in the manufacturing process can cause substantial manufacturing yield loss, and in some cases, cause production to be suspended. Manufacturing yields for new products initially tend to be lower as we complete product development and commence volume manufacturing, and typically increase as we bring the product to full production. Our forward product pricing includes this assumption of improving manufacturing yields and, as a result, material variances between projected and actual manufacturing yields will have a direct effect on our gross margin and profitability. The difficulty of accurately forecasting manufacturing yields and maintaining cost competitiveness through improving manufacturing yields will continue to be magnified by the increasing process complexity of manufacturing semiconductor products. Our manufacturing operations will also face pressures arising from the compression of product life cycles, which will require us to manufacture new products faster and for shorter periods while maintaining acceptable manufacturing yields and quality without, in many cases, reaching the longer-term, high-volume manufacturing conducive to higher manufacturing yields and declining costs.

We rely upon independent wafer fabrication facilities, called foundries, to provide silicon-based products and to supplement our gallium arsenide wafer manufacturing capacity. There are significant risks associated with reliance on third-party foundries, including:

Although we have long-term supply arrangements to obtain additional external manufacturing capacity, the third-party foundries we use for our standby manufacturing capacity may allocate their limited capacity to the production requirements of other customers. If we choose to use a new foundry, it will typically take an extended period of time to complete the qualification process before we can begin shipping products from the new foundry. The foundries may experience financial difficulties, be unable to deliver products to us in a timely manner or suffer damage or destruction to their facilities, particularly since some of them are located in earthquake zones. If any disruption of manufacturing capacity occurs, we may not

As the source of our technological and product innovations, our key technical personnel represent a significant asset. Our success depends on our ability to continue to attract, retain and motivate qualified personnel, including executive officers and other key management and technical personnel. The competition for management and technical personnel is intense in the semiconductor industry, and therefore we may not be able to continue to attract and retain the qualified management and other personnel necessary for the design, development, manufacture and

intellectual property rights to technologies that are important to our business and have demanded and may in the future demand that we license their technology or refrain from using it.

Any litigation to determine the validity of claims that our products infringe or may infringe intellectual property rights of another, including claims arising from our contractual indemnification of our customers, regardless of their merit or resolution, could be costly and divert the efforts and attention of our management and technical personnel. Regardless of the merits of any specific claim, we may not prevail in litigation because of the complex technical issues and inherent uncertainties in intellectual property litigation. If litigation were to result in an adverse ruling, we could be required to:

Despite these precautions, it may be possible for a third party to copy or otherwise obtain and use our technology without authorization, develop similar technology independently or design around our patents. If any of our intellectual property protection mechanisms fails to protect our technology, it would make it easier for our competitors to offer similar products, potentially resulting in loss of market share and price erosion. Even if we receive a patent, the patent claims may not be broad enough to adequately protect our technology. Furthermore, even if we receive patent protection in the United States, we may not seek, or may not be granted, patent protection in foreign countries. In addition, effective patent, copyright, trademark and trade secret protection may be unavailable or limited for certain technologies and in certain foreign countries.

Additionally, we are subject to risks in certain global markets in which wireless operators provide subsidies on handset sales to their customers. Increases in cellular handset prices that negatively impact handset sales can result from changes in regulatory policies or other factors, which could impact the demand for our products. Limitations or changes in policy on phone subsidies in South Korea, Japan, China and other countries may have additional negative impacts on our revenues.

Among our product portfolio, we manufacture and sell gallium arsenide semiconductor devices and components, principally power amplifiers and switches. The production of gallium arsenide integrated circuits is more costly than the production of silicon circuits. The cost differential is due to higher costs of raw materials for gallium arsenide and higher unit costs associated with smaller sized wafers and lower production volumes. Therefore, to remain competitive, we must offer gallium arsenide products that provide superior performance over their silicon-based counterparts. IfAlthough we manufacture and sell silicon-based power amplifiers, if we do not continue to offer GaAs products that provide sufficiently superior performance to justify the cost differential, our operating results may be materially and adversely affected. We expect the costs of producing gallium arsenide devices will continue to exceed the costs of producing their silicon counterparts. Silicon semiconductor technologies are widely used process technologies for certain integrated circuits and these technologies continue to improve in performance. We may not continue to identify products and markets that require performance attributes of gallium arsenide solutions.

Although we have invested in the past, and intend to continue to invest, significant resources in internal research and development activities, the complexity and rapidity of technological changes and the significant expense of internal research and development make it impractical for us to pursue development of all technological solutions on our own. On an ongoing basis, we review investment, alliance and acquisition prospects that would complement our product offerings, augment our market coverage or enhance our technological capabilities. We may not be able to identify and consummate suitable investment, alliance or acquisition transactions in the future. Moreover, if such transactions are consummated, they could result in:

Moreover, integrating acquired organizations and their products and services may be difficult, expensive, time-consuming and a strain on our resources and our relationship with employees and customers and ultimately may not be successful. Additionally, in periods following an acquisition, we will be required to evaluate goodwill and acquisition-related intangible assets for impairment. When such assets are found to be impaired, they will be written down to estimated fair value, with a charge against earnings.

We have certain anti-takeover measures that may affect our common stock. Our certificate of incorporation, our by-laws and the Delaware General Corporation Law contain several provisions that would make more difficult an acquisition of control of us in a transaction not approved by our Board of Directors. Our certificate of incorporation and by-laws include provisions such as:

In addition to the provisions in our certificate of incorporation and by-laws, Section 203 of the Delaware General Corporation Law generally provides that a corporation shallmay not engage in any business combination with any interested stockholder during the three-year period following the time that such stockholder becomes an interested stockholder, unless a majority of the directors then in office approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder or specified stockholder approval requirements are met.

None.

We are headquartered in Woburn, Massachusetts and have executive offices in Irvine, California. For information regarding property, plant and equipment by geographic region for each of the last two fiscal years, see Note 18 of Item 8 of this Annual Report on Form 10-K. The following table sets forth our principal facilities:

From time to time, various lawsuits, claims and proceedings have been, and may in the future be, instituted or asserted against the Company, including those pertaining to patent infringement, intellectual property, environmental, product liability, safety and health, employment and contractual matters.

Additionally, the semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to our business and have demanded and may in the future demand that we license their technology. The outcome of any such litigation cannot be predicted with certainty and some such lawsuits, claims or proceedings may be disposed of unfavorably to the Company. Generally speaking, intellectual property disputes often have a risk of injunctive relief, which, if imposed against the Company, could materially and adversely affect the Company’s financial condition, or results of operations. From time to time we are also involved in legal proceedings in the ordinary course of business.

We believe that there is no pending litigation involving the Company that will have, individually or in the aggregate, a material adverse effect on our business.
