Product Specification
PE4230
Product Description
The PE4230 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from DC through 3000 MHz. 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 PE4230 also exhibits input-output isolation of
better than 39 dB at 1000 MHz and is offered in a small 8-lead
MSOP package.
The PE4230 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.
