Skyworks introduces SKY77185 linear PA for WCDMA handsets

Skyworks Solutions Inc of Woburn, MA, USA has announced the launch of a new linear power amplifier (PA), the SKY77185, for wideband code division multiple access (WCDMA) handsets. Designed to address the European market for the universal mobile telecommunications system (UMTS) radio access network, the new PA is currently sampling.

According to Skyworks, the SKY77185 3 x 3 x 1 mm band 1 PA with integrated coupler is a fully matched, 10-pad surface mount module, offering full coverage of the 1920-1980 megahertz (MHz) bandwidth. The single GaAs MMIC contains all active circuitry in the module. It also contains on-board bias circuitry, as well as input and interstage matching circuits. The SKY77185 is manufactured using Skyworks’ InGaP GaAs HBT BiFET process, which provides for all positive voltage DC supply operation. Digital bias control can be used to optimize efficiency at high, mid and low power, says the company.

Thomas J. Richter, director of marketing at Skyworks, said: "Our high level of integration significantly reduces part size and bill-of-materials, while at the same time improving battery life - a win-win combination for our handset customers."

Samples of the SKY77185 are available, with volume production due to begin in July 2008.
