Product Specification
PE4243
SPDT UltraCMOS™ RF Switch
Product Description
The PE4243 UltraCMOS™ RF Switch is designed to cover a broad range of applications from near DC 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 +27 dBm can be achieved.
The PE4243 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.
