Product Specification

PE4237

Product Description

The PE4237 RF Switch is designed to cover a broad range of

applications from near DC to 4000 MHz. This reflective switch

integrates on-board CMOS control logic driven by a single-pin,

low voltage CMOS or TTL control input. Using a nominal +3-

volt power supply, a 1 dB compression point of +32 dBm can

be achieved. The PE4237 also exhibits outstanding isolation

of better than 43 dB at 1000 MHz and is

offered in a small 3x3 mm DFN package.

The PE4237 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.
