PE4232 Datasheet, PDF (1/8 Pages) Peregrine Semiconductor Corp. – SPST CATV UltraCMOS™ Switch

Product Description
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.
