QPA9822
3.3 - 4.2 GHz 0.5 Watt Linear 5G Pre-Driver
The QPA9822 is a wideband, high gain and high linearity driver amplifier. It provides 39dB gain at 3.5GHz and achieves a P1dB of 28dBm. The amplifier is designed to handle wideband 5G NR instantaneous signal bandwidths, making it perfectly suited for mMIMO applications.
The QPA9822 is internally match 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.
The QPA9822 is housed in a 16-pin 3.0 X 3.0 mm SMT package and is footprint and pin-compatible to QPA9120, QPA9121 and QPA9122M.
