Qorvo, a global provider of connectivity and power solutions, announced the industry’s highest gain pre-driver providing 39dB gain at 3.5 GHz and achieving a peak power of +29dBm. This new massive MIMO (mMIMO) pre-driver demonstrates Qorvo’s commitment to advancing 5G technology and further strengthens its position in cellular infrastructure.
The QPA9822 is a wideband, high gain, high linearity driver amplifier, engineered specifically for 32-node mMIMO systems. It is designed to enable wideband 5G New Radio (NR) instantaneous signal bandwidths of up to 530 MHz, making it ideally suited for the N77 band critical for 5G deployment and other mMIMO applications.
“Qorvo’s QPA9822 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 to ensure ease of deployment in popular bands in all geographies for 5G mMIMO systems,” said Debbie Gibson, Product Line Director of Qorvo’s Wireless Infrastructure business.
The QPA9822 is internally matched to 50 ohms (Ω) over the entire operating frequency band of 3.3 – 4.2 GHz and incorporates a fast enable/disable function through the VEN pin. It also offers external bias control capability for linearity optimization, supporting up to 530 MHz of instantaneous bandwidth.
Housed in a compact 16-pin, 3 x 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, thereby reducing time-to-market for customers. The QPA9822 and other new Qorvo products will be showcased at IMS 2024, Booth 1125, from 16-21 June in Washington, D.C.
