Skyworks Solutions Inc., an innovator of high performance analog and mixed signal semiconductors enabling mobile connectivity, announced several new front-end solutions supporting Qualcomm’s newest code division multiple access (CDMA) and HSDPA enhanced data for GSM evolution (HEDGE) reference platforms:


• The SKY77166 – a 450 megahertz (MHz) power amplifier (PA) for CDMA handsets and wireless local loop (WLL) applications in a 4 x 4 mm package – the smallest in the industry for applications in this frequency range. Skyworks is also working on defining a next-generation product that would drastically improve talk times in this growing market and will be designed to support certain Qualcomm chipsets.

• The SKY77183 (3 x 3 mm PA for the cellular band) and the SKY77184 (3 x 6 mm dual-band PA for cellular and PCS bands with integrated coupler) – Skyworks’ first PAs with full bypass mode. Routing the input signal directly from input to output bypasses the PA at low powers, enabling optimal operation at low output power levels and eliminating the need to supply current to the amplifier stages, resulting in significant savings in average battery current.

• The SKY77336 PAM – designed in a compact 5 x 5 mm form factor for quad-band cellular handsets for GSM, GPRS and EDGE.

At a higher level, this is the first time Skyworks is working directly with Qualcomm on handset platforms targeted for next-generation multimode handset manufacturers.

“We are delighted to be working with Qualcomm on several exciting and upcoming handset platforms, particularly given their innovative radio architectures and technology leadership position,” said David J. Aldrich, president and chief executive officer of Skyworks. “When combined with our core front-end capabilities, together we plan to deliver feature rich, best-in-class solutions to a number of the world’s leading handset OEMs and smartphone suppliers.”

The chipsets will support multiple wireless platform customers. The companies will manufacture these solutions, with mobile devices incorporating these designs available as early as later this year.
