Product Description
The PE4274 is an SPDT UltraCMOS⢠Switch designed for
Broadband applications such as CATV, DTV, Multi-Tuner
DVR (Digital Video Recorder), Set-top Box, PCTV and
Game Boxes. It offers high isolation and low insertion loss
in both a powered and a unique unpowered default state.
The PE4274 covers a broad frequency range from near DC
to beyond 2.2 GHz with a single positive supply and CMOS
control. The PE4274 provides a smaller, cost effective,
more reliable and manufacturable alternative to mechanical
relays in some set-top box applications.
The PE4274 is manufactured in Peregrineâs patented Ultra
Thin Silicon (UTSi®) CMOS process, offering the
performance of GaAs with the economy and integration of
conventional CMOS.
