Product Specification

PE4245

SPDT UltraCMOS™ RF Switch

DC - 4000 MHz

Product Description

The PE4245 RF Switch is designed to cover a broad range of

applications from near DC to 4000 MHz. 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 PE4245 also exhibits excellent isolation of

better than 42 dB at 1000 MHz and is offered in a small 3x3

mm DFN package.

Features

• Single 3.0 V Power Supply

• Low insertion loss: 0.6 dB at 1000 MHz,

0.7 dB at 2000 MHz

• High isolation of 42 dB at 1000 MHz,

32 dB at 2000 MHz

• Typical 1 dB compression of +27 dBm

• Single-pin CMOS logic control

The PE4245 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.

• Available in a 6-lead DFN package
