  • Housed in a compact 16-pin, 3 x 3 mm SMT package
  • Footprint and pin-compatible with the QPA9122M high-gain and high-linearity driver amplifier

The QPA9822 is a wideband, high-gain, high-linearity driver amplifier designed specifically for 32-node massive MIMO (mMIMO) systems. It supports wideband 5G New Radio (NR) instantaneous signal bandwidths of up to 530 MHz, making it ideal for the N77 band, which is critical for 5G deployment and other mMIMO applications. It not only delivers the highest gain available on the market for 5G pre-drivers today but also provides a scalable solution for 32T and 64T radios. This helps ensure ease of deployment in popular bands across all geographies for 5G mMIMO systems.

The driver is internally matched to 50 ohms (Ω) across its operating frequency band of 3.3 – 4.2 GHz and features a fast enable/disable function through the VEN pin. It also offers external bias control for linearity optimization, supporting up to 530 MHz of instantaneous bandwidth. This compatibility allows for easy integration into both existing and new designs, reducing time-to-market for customers.
