Product Specification
PE4256
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 Peregrineâs UltraCMOSâ¢
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.
