Product Specification

PE4239

SPDT UltraCMOS™ RF Switch

Features

Product Description

• Single-pin or complementary CMOS

The PE4239 UltraCMOS™ RF Switch is designed to cover a

broad range of applications from DC through 3.0 GHz. This

reflective switch integrates on-board CMOS control logic with a

low voltage CMOS-compatible control interface, and can be

controlled using either single-pin or complementary control

inputs. Using a nominal +3-volt power supply voltage, a typical

input 1 dB compression point of +27 dBm can be achieved.

logic control inputs

• +3.0-volt power supply needed for

single-pin control mode

• Low insertion loss: 0.7 dB at 1.0 GHz,

0.9 dB at 2.0 GHz

• Isolation of 32 dB at 1.0 GHz, 23 dB at

2.0 GHz

The PE4239 UltraCMOS™ 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.

• Typical input 1 dB compression point of

+27 dBm

• Ultra-small SC-70 package
