The QPA8840 is a an ultra-linear, 22 dB Gain, GaAs amplifier, intended for mid or output stage amplification in CATV infrastructure applications. The QPA8840 operates off a 12 Volt, 425 mA supply. The device features a pushpull cascode design which provides flat gain along with ultra-low distortion from 50 MHz to 1.8 GHz.
