The PE4232 is a is a high-isolation Switch designed for CATV

applications, covering a broad frequency range from near DC

up to 1300 MHz. This single-supply SPST switch offers a

single-pin CMOS control interface with industry leading CTB

performance. It also provides low insertion loss, high isolation

and extremely low bias requirements while operating on a

single 3-volt supply. In a typical CATV application, the PE4232

provides for a cost effective and manufacturable solution vs.

mechanical relays.

The PE4232 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.
