Qorvo QPA9822 linear 5G high-gain, high-drive amplifier

Qorvo has released its QPA9822 linear 5G high-gain, high-drive amplifier. The product is engineered specifically for 32-node massive multiple-input and multiple-output (mMIMO) systems found in wideband 5G, new radio (NR), instantaneous signal bandwidths, and mobile infrastructure applications.

The amplifier is designed to enable wideband 5G, NR, instantaneous signal bandwidths of up to 530 MHz, making it suitable for the N77 band critical for 5G deployment and other mMIMO applications. It provides a 39 dB gain at 3.5 GHz and achieves a peak power of +29 dBm. It is internally matched to 50Ω over the entire operating frequency band of 3.3 to 4.2 GHz and incorporates a fast enable/disable function through the VEN pin.

The product 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 device is footprint and pin-compatible with the QPA9122M high-gain and high-linearity driver amplifier, allowing for easy integration into existing and new designs, and easy deployment in popular bands in all geographies for 5G mMIMO systems.
