Skyworks Launches High-Isolation Absorptive Switch For Base Station Applications

Woburn, MA -- Skyworks Solutions, Inc. introduced its highest isolation switch with low loss system performance for the cellular infrastructure market. Targeted at OEMs building high performance, multi-channel systems, the SKY13286-359LF is suitable for base station applications where synthesizer isolation is critical, minimizing the blending of one frequency into the circuitry of another. The company's high isolation switches, which integrate silicon complementary metal-oxide semiconductor (CMOS) drivers, also require fewer components.

"Skyworks' high isolation switch is pushing the performance envelope. By leveraging key pHEMT process technologies, our solution gives designers much more freedom in selecting circuit architectures that meet demanding performance requirements for both isolation and insertion loss," said Stan A. Swearingen, vice president and general manager of Linear Products for Skyworks. "With several design wins and other customer evaluations ongoing, Skyworks is pleased to be providing an innovative switch solution for the rapidly growing cellular infrastructure market."

Enabled by Skyworks' patent pending sixth-generation pseudomorphic high electron mobility transistor (pHEMT) process, the SKY13286-359LF is a gallium arsenide (GaAs) FET integrated circuit high isolation absorptive switch in a 4 x 4 mm 16-lead QFN with exposed pad plastic package. Other features include single positive voltage control, matched inputs and outputs, and lead-free, restriction of hazardous substances (ROHS)-compliant packaging.
