Product Specification
PE42742
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 near DC 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.
