The QPA9903 is a high-efficiency, linearizable power amplifier targeting Band 3 small-cell wireless infrastructure systems. Using InGaP/GaAs HBT technology, the product delivers high efficiency of 33.8% at +28dBm average output power while providing excellent DPD linearized ACPR of -50dBc for signal bandwidths of up to 60MHz.
The QPA9903 is housed in a 5x5mm SMT package. It is pin-to-pin compatible to QPA9908 (band 8 high-efficiency small cell PA).
