Skyworks Solutions announces new solutions for its Intera family of front-end modules addressing WCDMA applications that support bands I, II, IV, V and VI . The company’s WCDMA FEMs simplify RF design, reduce critical board space through higher levels of integration, extend battery life, and facilitate implementation within virtually any baseband architecture. Skyworks’ patent-pending bulk acoustic wave filter, which the company has already sampled to various multimode handset customers, is also leveraged in personal communications system bands I, II and IV ─ creating a complete RF solution for handsets when combined with the company’s switches, power amplifiers, front-end modules and transceivers. BAW filters are integral components of radio frequency architectures. Given their combination of small footprint and low profile, they are valuable in enabling next-generation wireless products which increasingly require greater multimedia functionality and reduced form factors.

Skyworks’ portfolio of Intera FEMs support four of the five tier-one handset OEMs, and are at the heart of over 200 million handsets following their debut just three and a half years ago. Leveraging patented load insensitive power amplifier technology, the company’s newest WCDMA FEMs with fully integrated filters, completely address operators’ requirements for 3G multimode, multimedia applications where size, performance and cost are critical.

WCDMA is a 3G wireless technology that allows users to send and receive mobile voice, data, image and video communications at speeds up to 2 megabytes per second (Mbps) over a broad range of frequencies. According to Deutsche Bank, WCDMA handsets are expected to grow from 45 million handsets in 2005 to 445 million units in 2009.

Skyworks’ family of WCDMA FEMs support high speed uplink packet access, high speed downlink packet access, have a built-in power coupler and detector, and reduce manufacturers’ overall bill-of-materials. More specifically:
- The SKY77433 for Band I is a fully matched 16-pin, full-duplex FEM in a small and efficient 4 x 7 mm package for universal mobile telecommunications systems in Europe and Asia ─ also identified as the international mobile telecommunications 2000.
- The SKY77434 for Band II is a 4 x 7 mm FEM for U.S. PCS applications.
- The SKY77435 for Band IV is a 4 x 7 mm FEM for advanced wideband systems, otherwise known as the Federal Communications Commission Auctioned Spectrum.
- The SKY77436 for Band V is a 4 x 7 mm FEM for the U.S. Cellular market, while Band VI is developed for Japan.
