Product Specification

PE4231

SPDT High Power UltraCMOS™

Product Description

DC – 1.3 GHz RF Switch

The PE4231 SPDT High Power UltraCMOS™ RF Switch is

designed to cover a broad range of applications from DC to 1.3

GHz. This single-supply reflective switch integrates on-board

CMOS control logic driven by a simple, single-pin CMOS or

TTL compatible control input. Using a nominal +3-volt power

supply, a typical input 1 dB compression point of +32 dBm can

be achieved. The PE4231 also exhibits input-output isolation of

better than 42 dB at 1.0 GHz and is offered in a small 8-lead

MSOP package.

Features

• Optimized for 75 Ω systems

• Single +3-volt power supply

• Low insertion loss: 0.80 dB at 1.0 GHz

• High isolation: 42 dB at 1.0 GHz

• Typical input 1 dB compression point of

+32 dBm

• Single-pin CMOS or TTL logic control

• Low cost

The PE4231 SPDT High Power UltraCMOS™ RF Switch 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.
