Product Description
The PE4272 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. The device offers a
simple alternative solution to pin diode and mechanical relay
switches.
The PE4272 SPDT High Power 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.
