High Gain mMIMO Driver Amplifier from Qorvo

High Gain mMIMO Driver Amplifier: QPA9122M

October 14, 2021

RFMW announced design and sales support for a high gain and high linearity driver amplifier. The Qorvo QPA9122M provides 36.5 dB gain at 2.6 GHz and achieves a peak power of 27 dBm P3dB. The amplifier can provide good DPD linearity performance with up to 200 MHz wide 5G NR signals, making it perfectly suited for 5G mMIMO applications, TDD/FDD systems and wireless infrastructure systems. The QPA9122M is internally match to 50 Ω over the entire operating frequency band of 2.3 to 5.0 GHz and incorporates a shut-down function through the VPD pin. External bias control allows for linearity optimization. Housed in a 16-pin 3 x 3 mm SMT package.
