Product Description
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.
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.
