QPA8801 75 11dB CATV Push Pull Amplifier (451218MHz) ) 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 380mA from a single +12V supply providing approximately 11dB gain with excellent linearity. Users may adjust the bias current with external voltage enabling the QPA8801 to be used in 40P 5x7 QFN Package applications such as doublers or for lower power system applications. The QPA8801 is packaged in an industry standard 40-pin 5 x 7mm QFN package with exposed paddle (EP) beneath the device for thermal and electrical grounding.
