QPA4425

75Ω 25dB CATV Amplifier 47 – 1218MHz

Product Overview

The QPA4425 is a GaAs pHEMT/MESFET 75-ohm

push-pull RF amplifier IC featuring 25dB of flat gain

and low noise. This IC is designed to support DOCSIS

3.1 applications up to 1218MHz using a single 24V

supply. The QPA4425 offers low noise and low

distortion at high efficiency consuming only 7W in a

5x7 QFN package. Its compact size and low ϴjc

enable integration that is ideally suited for hybrid

module applications.
