QPA9822: High Gain and High Linearity Pre-Driver for 5G MIMO Systems
Qorvo has announced the new gain pre-driver QPA9822, 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 as a leader in cellular infrastructure. It 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.
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.
