The Qorvo QPA9903 is a high-efficiency, linearisable power amplifier targeting Band 3 (1805 – 1880 MHz frequency range) small-cell wireless infrastructure systems.
Using InGaP/GaAs HBT technology, the product delivers high efficiency of 35 per cent at +28dBm average output power while providing excellent DPD linearized ACPR of -50dBc for signal bandwidths of up to 60MHz.
The QPA9903 is matched to 50 ohms and housed in a 5x5mm SMT package. It is pin-to-pin compatible with QPA9908 (band 8 high-efficiency small cell PA). This device also serves m-MIMO and DAS systems.
