The PE4274 is an SPDT UltraCMOSTM 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 Peregrine's patented Ultra Thin Silicon (UTSi) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.
