Product Specification
PE42421
SPDT UltraCMOS™
10 MHz – 3.0 GHz RF Switch
Product Description
The PE42421 UltraCMOS™ RF Switch is designed to
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
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.
