QPA8801

75Ω 11dB CATV Push Pull Amplifier 45 – 1218MHz

Product Overview

The QPA8801 is an ultra-linear, QFN GaAs amplifier

MMIC intended for output stage amplification in CATV

infrastructure applications. The device features a push-pull

cascode design which provides flat gain along with ultra-

low distortion, making it ideal for use in CATV distribution

systems requiring high output power capability. The

QPA8801 draws approximately 380 mA from a single

+12 V supply providing ~11 dB gain with excellent

linearity. Users may adjust the bias current with external

voltage enabling the QPA8801 to be used in applications

such as doublers or for lower power system applications.

The QPA8801 is packaged in an industry standard 40 pin

5 x 7 mm QFN package with exposed paddle (EP)

beneath the device for thermal and electrical grounding
