The QPA9822 is a wideband, high gain and high linearity driver amplifier. It provides 39 dB gain at 3.5 GHz and achieves a P1dB of 28 dBm. The amplifier is designed to handle wideband 5G NR instantaneous signal bandwidths, making it perfectly suited for mMIMO applications. The QPA9822 is internally matched to over the entire operating frequency band of 3.3 to 4.2 GHz and incorporates a fast enable/disable function through the VEN pin. QPA9822 also has external bias control capability for linearity optimization.
