The PE4240 is a high-isolation MOSFET Switch designed for

CATV applications, covering a broad frequency range from

DC up to 1.3 GHz. 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

PE4240 provides for a cost effective and manufacturable

solution vs. mechanical relays.

The PE4240 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.
