QPB8858

75Ω 34dB CATV Amplifier 47 – 1218MHz

Product Overview

The QPB8858 is a GaAs pHEMT/MESFET 75-ohm

push-pull RF amplifier IC featuring over 34dB 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 QPB8858 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.
