QPB8857

75Ω 28dB CATV Doubler Amplifier 47 – 1218MHz

Product Overview

The QPB8857 is a GaAs pHEMT/MESFET 75-ohm

Doubler RF amplifier IC featuring over 28dB 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 QPB8857 offers low noise and

low distortion at high efficiency consuming only 10.5W

in a 5x7 QFN package. Its compact size and low ϴjc

enable integration that is ideally suited for hybrid

module or an alternative to hybrid module

applications.
