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.

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