Product Specification

PE4244

SPDT UltraCMOS™ RF Switch

Features

Product Description

•

Single +3.0-volt Power Supply

The PE4244 UltraCMOS™ RF Switch is designed to cover a

broad range of applications from DC to 3.0 GHz. This switch

integrates on-board CMOS control logic with a low voltage

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

supply voltage, a 1 dB compression point of +27 dBm can be

achieved. The PE4244 also exhibits excellent isolation of 39 dB

at 1.0 GHz and is offered in a small 8-lead MSOP package.

Low Insertion loss: 0.60 dB up to

2.0 GHz

•

High isolation of 39 dB at 1.0 GHz,

29 dB at 2.0 GHz

•

Typical 1 dB compression of +27 dBm

Single-pin CMOS logic control

Packaged in 8-lead MSOP

The PE4244 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.
