PE4273 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor Corp. – SPDT Broadband UltraCMOS™ DC - 3 GHz RF Switch

Product Description
The PE4273 RF Switch is designed for the TV tuner,
PCTV, set top box, DTV, DVR and general broadband
applications. This device offers industry leading
broadband linearity, 1.5 kV ESD tolerance and a
simple CMOS interface. It offers a simple alternative
solution to pin diode and mechanical relay switches.
The PE4273 SPDT Broadband RF Switch is
manufactured on Peregrine’s UltraCMOS^® process, a
patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the
performance of GaAs with the economy and
integration of conventional CMOS.
