Skyworks Solutions Inc of Woburn, MA, USA has announced several new front-end solutions supporting Qualcomm’s newest code division multiple access (CDMA) and high-speed downlink packet access (HSDPA) enhanced data for GSM evolution (HEDGE) reference platforms:

• The SKY77166 is a 450MHz power amplifier (PA) for CDMA handsets and wireless local loop (WLL) applications in a 4mm x 4mm package - the smallest in the industry for applications in this frequency range, the firm claims. 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 (a 3mm x 3mm PA for the cellular band) and the SKY77184 (a 3mm x 6mm dual-band PA for cellular and PCS bands with integrated coupler) are Skyworks’ first PAs with full bypass mode. Routing the input signal directly from input to output bypasses the PA at low powers. This enables optimal operation at low output power levels and eliminates the need to supply current to the amplifier stages, resulting in significant savings in average battery current, the firm claims.

• The SKY77336 power amplifier module (PAM) is designed in a compact 5mm x 5mm 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.

“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,” says Skyworks’ president and CEO David J. Aldrich. The chipsets will support multiple wireless platform customers.

Mobile devices incorporating these designs should be available later this year.
