Product Specification
PE4244
Product Description
SPDT UltraCMOS® RF Switch
10 – 3000 MHz
The PE4244 UltraCMOS® RF switch is designed to cover a
Features
broad range of applications from 10 to 3000 MHz. This switch
integrates on-board CMOS control logic with a low voltage
Single +3.0-volt Power Supply
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
n isolation of 39 dB at 1.0 GHz and is offered in a small 8-lead
MSOP package.
ig The PE4244 UltraCMOS® RF switch is manufactured in
Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS
s 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.
