The PE4239 UltraCMOS™ RF Switch is designed to cover a

broad range of applications from DC through 3.0 GHz. This

reflective switch integrates on-board CMOS control logic with a

low voltage CMOS-compatible control interface, and can be

controlled using either single-pin or complementary control

inputs. Using a nominal +3-volt power supply voltage, a typical

input 1 dB compression point of +27 dBm can be achieved.

The PE4239 UltraCMOS™ RF Switch is manufactured on

Peregrine’s UltraCMOS™ process, a patented variation of

silicon-on-insulator (SOI) technology on a sapphire substrate,

offering the performance of GaAs with the economy and

integration of conventional CMOS.
