The QPA3908 is a fully integrated two-stage Doherty power amplifier module designed for massive MIMO applications with 8 W RMS at the device output covering frequency range from 3.7 to 3.98 GHz. The module is 50 Ω input and output and requires minimal external components. The module is also compact and offers a much smaller footprint than traditional discrete component solutions. The QPA3908 incorporates a driver and Doherty final stage delivering high power added efficiency for the entire module at 8W average power.
