Product Description
The PE4259 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 +33.5 dBm can be achieved.
The PE4259 SPDT High Power 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.
