cover a broad range of applications from 10 MHz

through 3000 MHz. 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

+33.5 dBm can be achieved.

The PE42421 SPDT RF switch is manufactured on

variation of silicon-on-insulator (SOI) technology on

a sapphire substrate, offering the performance of

GaAs with the economy and integration of

conventional CMOS.
