The QPA9942 is a high-efficiency, linearizable power amplifier targeting Band 42 small-cell wireless infrastructure systems. Using InGaP/GaAs HBT technology, the product delivers high efficiency of 26% at +28dBm average output power while providing excellent DPD linearized ACPR of -50dBc for wide band 5G signals.
The QPA9942 is housed in a 5.0 x 5.0 mm SMT package. It is pin-to-pin compatible to QPA9908, QPA9901 and QPA9903 (high-efficiency small cell PA).
