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
