Qorvo Launches Industry's Best High-Gain 5G mMIMO Pre-Driver

[xiaomo]

Qorvo®, a leading global provider of connectivity and power solutions, recently announced the launch of the industry's best high-gain 5G pre-driver, the QPA9822. The product can achieve a high gain of 39dB at 3.5GHz and a peak power of +29dBm. This new pre-driver for mMIMO base stations demonstrates Qorvo's firm commitment to promoting the development of 5G technology and further consolidates its leadership in cellular infrastructure.

As a wideband, high-gain, high-linearity driver amplifier, the QPA9822 is designed for 32-node mMIMO systems. It can achieve up to 530MHz of 5G New Radio (NR) instantaneous signal bandwidth, which is very suitable for the N77 band that is critical to 5G deployment and other mMIMO applications.

"Qorvo's QPA9822 not only provides the best high gain that can be achieved by 5G pre-drivers on the market today, but also creates a scalable solution for 32T and 64T wireless base stations. This helps ensure that 5G mMIMO systems are easily deployed in popular bands around the world." said Debbie Gibson, product line director of Qorvo's Wireless Infrastructure Business Unit.

The QPA9822 is internally matched to 50Ω impedance across the entire operating band of 3.3-4.2GHz and integrates a fast enable/disable function through the VEN pin. In addition, it also has external bias control capabilities to optimize linearity and support up to 530MHz of instantaneous bandwidth.

The QPA9822 uses a compact 16-pin, 3mm×3mm SMT package, which is size and pin compatible with the QPA9122M high-gain, high-linearity driver amplifier, and can be easily integrated into existing and new designs, thereby shortening the time to market for customers.
