Preliminary Specification

PE4274

75Ω Terminated - 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
