Product Specification
PE4231
Product Description
The PE4231 SPDT High Power UltraCMOS™ RF Switch is
designed to cover a broad range of applications from DC to 1.3
GHz. This single-supply reflective 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 +32 dBm can
be achieved. The PE4231 also exhibits input-output isolation of
better than 42 dB at 1.0 GHz and is offered in a small 8-lead
MSOP package.
The PE4231 SPDT High Power 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.
