Product Specification

PE4220

SPDT UltraCMOS™ RF Switch

DC - 2500 MHz

Product Description

Features

The PE4220 UltraCMOS™ RF Switch is designed to cover a

broad range of applications from near DC to 2500 MHz. This

single-supply 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 +22 dBm can be achieved. The

PE4220 also exhibits input-output isolation of better than 37 dB

at 1000 MHz and is offered in a small 8-lead MSOP package.

• Single 3-volt power supply

• Very low insertion loss: 0.25 dB at

1000 MHz

• High isolation: 37 dB at 1.0 GHz

• Typical input 1 dB compression point

of +22.5 dBm

• Single-pin CMOS or TTL logic control

• Packaged in a small 8-lead MSOP

The PE4220 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.

Notes:

1. Device linearity will begin to degrade below 10 MHz.

2. The DC transient at the output of any port of the switch when the control voltage is switched from Low to High or High to Low

in a 50Ω test set-up, measured with 1ns risetime pulses and 500 MHz bandwidth.
