Product Specification
PE4273
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.
