Product Description
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.
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.
