Product Description

The PE4256 is an UltraCMOS™ Switch designed for CATV

applications, covering a broad frequency range from 5 MHz up to

3 GHz. This single-supply SPDT switch integrates a two-pin

CMOS control interface. It also provides low insertion loss with

extremely low bias requirements while operating on a single 3-

volt supply. In a typical CATV application, the PE4256 provides

for a cost effective and manufacturable solution when compared

to mechanical relays.

The PE4256 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.
