Business Wire
Skyworks Solutions, Inc. (NASDAQ:SWKS), an innovator of high
performance analog and mixed signal semiconductors enabling mobile
connectivity, today unveiled a new high-efficiency linear power
amplifier (PA) for wideband code division multiple access (WCDMA)
handsets. The SKY77185, designed to address European market needs
for the universal mobile telecommunications system (UMTS) radio
access network, is currently sampling. Skyworks has shipped over 50
million WCDMA PAs as of December 2007. Skyworks drastically reduced
bill-of-materials (BOM) by including an integrated coupler for
power control � typically a discrete component on the reference
design. In addition, the PA produces high power added efficiency
(PAE) at mid power which significantly increases talk times.
�Skyworks leadership 3G portfolio is unparalleled,� said Thomas J.
Richter, director of marketing at Skyworks. �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.� About the SKY77185 The
SKY77185 3 x 3 x 1 mm band 1 PA with integrated coupler is a fully
matched, 10-pad surface mount module developed for WCDMA
applications. This small and efficient PA packs full coverage of
the 1920-1980 megahertz (MHz) bandwidth into a single compact
package. Due to high efficiencies attained throughout the entire
power range, the solution delivers unsurpassed talk-time
advantages. The single gallium arsenide (GaAs) microwave monolithic
integrated circuit (MMIC) contains all active circuitry in the
module. The MMIC contains on-board bias circuitry, as well as input
and interstage matching circuits. The device is manufactured using
the company�s InGaP GaAs heterojunction bipolar transistor (HBT)
BiFET process that provides for all positive voltage direct current
(DC) supply operation while maintaining high efficiency and
linearity. Digital bias control can be used to optimize efficiency
at high, mid and low power. Pricing and Availability Samples of the
SKY77185 FEM are currently available, with volume production
scheduled for July 2008. For customized pricing, please contact

will be showcasing its portfolio of Intera� FEMs and Helios� radio
solutions in Hall 8, Stand C132 at Mobile World Congress, being
held February 11-14. About Skyworks Skyworks Solutions, Inc. is an
