Product Specification

PE4256

75 Ω SPDT CATV UltraCMOS™

Switch 5 MHz - 3 GHz

Product Description

Features

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.

 75 Ω characteristic impedance

 Integrated 75 Ω terminations

 CTB performance of -90 dBc

 High isolation 65 dB at 1000 MHz

 Low insertion loss: typically 0.5 dB at 5

MHz, 0.9 dB at 1000 MHz

 High input IP3: >50 dBm

 CMOS two-pin control

 Single +3 volt supply operation

 Low current consumption: 8 μA

 Unique all off terminated mode

 4 x 4 mm QFN package

The PE4256 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.
