PE4243 Datasheet, PDF (1/8 Pages) Peregrine Semiconductor Corp. – 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.
