A massive MIMO (mMIMO) predriver from Qorvo, the QPA9822 provides gain of 39 dB at 3.5 GHz and output power of 28 dBm P1dB. The linear driver amplifier enables wideband 5G NR instantaneous signal bandwidths of up to 530 MHz. This makes it well-suited for the n77 band used for 5G deployment and other mMIMO applications.

The QPA9822 is internally matched to 50 Ω over the entire operating frequency range of 3.3 GHz to 4.2 GHz. It offers an enable/disable function through the VEN pin for time-division duplexing (TDD) operation.
The part, which operates from a 5-V supply, is housed in a 3×3-mm, 16-pin surface-mount package. The QPA9822 is both footprint and pin-compatible with the company’s QPA9122M driver amplifier to allow easy integration into existing and new designs.
