UltraCMOS® SPDT CATV Switch

PE42742

RF Switch, SPDT, 0.005 to 2.2 GHz, 0.75 to 1.1 dB IL, 70.5 to 76 dB Isolation, 33 dBm Pwr Rating, QFN, 75 Ohm

Status: Standard | Data Sheet:

| RoHS Compliance: Rohs Compliant

Part number PE42742 Product Type RF Switch from Manufacturer pSemi

Description

The PE42742 is an SPDT UltraCMOS® switch designed for broadband applications such as CATV, DTV, multi-tuner DVR, 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.
