PE42742MLIBB-Z Datasheet, PDF (1/10 Pages) Peregrine Semiconductor – 75 Ω Terminated, 5 - 2200 MHz SPDT CATV UltraCMOS™ Switch Featuring Unpowered Operation

Product Description
The PE42742 is an SPDT UltraCMOS™ switch designed
for broadband applications such as CATV, DTV, Multi-
Tuner DVR (Digital Video Recorder), Set-top Box, PCTV
and Game Boxes. It meets FCC 15.115 spec of 80 dB
isolation @ 216 MHz and offers high isolation and low
insertion loss in both a powered and a unique unpowered
default state. The PE42742 covers a broad frequency
range from 5 MHz to beyond 2200 MHz with a single
positive supply and CMOS control. It provides a smaller,
cost effective, more reliable and manufacturable
alternative to mechanical relays in set-top box
applications.
The PE42742 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.
