PE4274
Product Description
The PE4274 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 offers high isolation and low insertion loss in both a powered and a unique unpowered default state. The PE4274 covers a broad frequency range from near DC to beyond 2.2 GHz with a single positive supply and CMOS control. The PE4274 provides a smaller, cost effective, more reliable and manufacturable alternative to mechanical relays in some set-top box applications. The PE4274 is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. 75 Terminated - 2.2 GHz SPDT CATV UltraCMOS Switch Featuring - Unpowered Operation Features Unpowered operational state All-Off terminated state CTB performance of 90dBc High isolation 63 dB at 1 GHz Low insertion loss: typically 0.5 dB at 5 MHz, 0.8 dB at 1 GHz CMOS two-pin control Single +3 volt supply operation 1 kV ESD Low current consumption: 8 A
