Qorvo unveils industry’s highest gain pre-driver for 5G mMIMO
Qorvo has announced the industry’s highest gain pre-driver providing 39dB gain at 3.5 GHz and achieving a peak power of +29dBm.
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.
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 optimisation, 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.
