Samsung Using Skyworks Products For Femtocell Applications

Woburn, MA -- Skyworks Solutions, Inc. announced that Samsung is leveraging multiple solutions from its Linear Products portfolio including transceivers, power amplifiers and LNAs for use in FEMTO cell applications. FEMTO cells, or small cellular base stations designed for residential and small business environments, help provide enhanced coverage in wireless networks and solve very real, near-term signal coverage and capacity issues. According to In-Stat, worldwide FEMTO cell subscriptions (installed devices) are expected to grow to 40 million by 2011 and surpass 100 million end-users over the next five years, representing a market opportunity for FEMTO cell devices of over $4 billion.

"Skyworks is uniquely suited to support the demanding system requirements of FEMTO cells given our technology breadth and depth," said Stan Swearingen, Skyworks' vice president and general manager of Linear Products. "In fact, the architecture being utilized for Samsung's FEMTO cell systems is an example of our ability to leverage proven and innovative technology across diverse markets."

Products entering volume production include, among others, the:

• SKY74068: highly integrated transmitter for dual-band CDMA applications operating in cellular CDMA, AMPS, and PCS modes. The only external components needed for operation are bias resistors, bypass capacitors, and passives for the PLL loop filter.

• SKY74092: a highly integrated CDMA/PCS LNA for dual-band and tri-mode. The device provides low noise amplification with high linearity to achieve a high dynamic range. Up to four gain steps of low noise amplification are supported through a three-wire read/write serial bus interface.

• SKY74100: a highly integrated receiver for tri-band CDMA applications with GPS capability.

• SKY77410: a load insensitive power amplifier (LIPA(TM)) module for WCDMA applications that meets stringent spectral linearity requirements with high power added efficiency for power output of up to 27.5 dBm, even with a load mismatch of 4:1 VSWR -- eliminating the need for an isolator.
