Pre-driver claims high gain for 5G mMIMO

Qorvo, Inc. has announced the QPA9822, claiming the industry’s highest gain 5G massive MIMO (mMIMO) pre-driver. Providing 39-dB gain at 3.5 GHz and a peak power of +29 dBm, the QPA9822 high-gain and high-linearity driver amplifier enables wideband 5G New Radio (NR) instantaneous signal bandwidths of up to 530 MHz, making it suitable for the N77 band critical for 5G deployment and other mMIMO applications. Applications include 5G mMIMO, mobile infrastructure, general-purpose wireless and TDD/FDD systems.

Designed for 32-node mMIMO systems, the 5G pre-driver provides a scalable solution for 32T and 64T radios, making it easy to deploy in popular bands in all geographies for 5G mMIMO systems. Key specs include 3.3 – 4.2-GHz operational frequency, 50-Ω matched RF input and output and +5-V single supply (ICQ adjustable). Other features include fast enable/disable for TDD operation, DC power shutdown and an external bias control capability for linearity optimization, supporting up to 530 MHz of instantaneous bandwidth.

Housed in a compact 16-pin, 3 × 3 mm SMT package, the QPA9822 is footprint and pin-compatible with the QPA9122M high-gain and high-linearity driver amplifier, allowing for easy integration into existing and new designs, reducing time-to-market for customers, Qorvo said.

Qorvo will showcase the QPA9822 at IMS 2024, June 16-21, Washington, D.C., in booth #1125. Click here for more information.
