3.3 – 4.2 GHz 0.5 Watt Linear 5G Pre-Driver: QPA9822
Source: Qorvo

The QPA9822 is a wideband, high-gain, and high-linearity driver amplifier designed to handle wideband 5G NR instantaneous signal bandwidths, making it perfectly suited for m-MIMO applications.
The QPA9822 provides 39dB gain at 3.5GHz and achieves a P1dB of 28dBm. It is internally matched to 50Ω over the entire operating frequency band of 3.3 – 4.2 GHz and incorporates a fast enable/disable function through the VEN pin.
QPA9822 also has external bias control capability for linearity optimization, and is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120, QPA9121 and QPA9122M.
