Preliminary Specification  
PE4274  
75Terminated - 2.2 GHz SPDT  
CATV UltraCMOS™ Switch  
Product Description  
Featuring - Unpowered Operation  
Features  
Unpowered operational state  
All-Off terminated state  
CTB performance of 90dBc  
High isolation 63 dB at 1 GHz  
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.  
Low insertion loss: typically 0.5 dB at  
5 MHz, 0.8 dB at 1 GHz  
CMOS two-pin control  
Single +3 volt supply operation  
1 kV ESD  
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.  
Low current consumption: 8 µA
