PRELIMINARY SPECIFICATION
PE84244
Military Operating Temperature Range
Product Description
The PE84244 MOSFET 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 PE84244 also exhibits excellent
isolation of 28 dB at 2.0 GHz and is offered in a small 8-lead
MSOP package.
The PE4244 MOSFET 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.
