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.

Recommended Mounting Pattern



Ensure good package backside paddle solder attach for reliable operation and best electrical performance.

Place mounting screws near the part to fasten a back-side heat sink.

Do not apply solder mask to the back side of the PC board in the heat sink contact region.

Ensure that the backside via region makes good physical contact with the heat sink.
