Product Specification

PE4273

SPDT Broadband UltraCMOS™

DC – 3 GHz RF Switch

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.

Features

• Single-pin or complementary CMOS logic

control inputs

• High ESD tolerance of 1.5 kV

• Low insertion loss: 0.50 dB at 1000 MHz,

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.

0.65 dB at 2000 MHz

• Isolation of 34.5 dB at 1000 MHz, 25 dB at

2000 MHz

• Typical input 1 dB compression point of

+32 dBm

• Ultra-small SC-70 package
