Product Specification

PE4280

75 Ω SPDT CATV UltraCMOS™ Switch

DC—2.2 GHz

Product Description

The PE4280 is an UltraCMOS™ Switch designed for CATV

applications, covering a broad frequency range from DC up to

2.2 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 V

supply. In a typical CATV application, the PE4280 provides for

a cost effective and manufacturable solution when compared to

mechanical relays.

Features

• 75 Ω characteristic impedance

• Integrated 75 Ω 0.25 watt terminations

• CTB performance of 85 dBc

• High isolation 60 dB at 1 GHz

• Low insertion loss: typically 0.5 dB at

5 MHz, 1.1 dB at 1 GHz

• High input IP3: 50 dBm

The PE4280 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.

• CMOS two-pin control

• Single +3 V supply operation

• Low current consumption: 8 µA

• Unique all off terminated mode

• 4x4 mm QFN package
