Product Specification
PE4242
SPDT UltraCMOS鈩?RF Switch
Product Description
The PE4242 UltraCMOS鈩?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 PE4242 RF Switch is manufactured on Peregrine鈥檚
UltraCMOS鈩?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.
