The QPA9122M is a wideband, high gain and high linearity driver amplifier. It provides 36.5dB gain at 2.6GHz and achieves a peak power of 27dBm P3dB. The amplifier can provide good DPD linearity performance with wideband signals of up to 200 MHz wide 5G NR signals, making it perfectly suited for mMIMO applications.
The QPA9122M is internally match to 50Ω over the entire operating frequency band of 2.3 - 5.0 GHz and incorporates a shut-down function through the VPD pin.
QPA9122M also has external bias control capability for linearity optimization.
The QPA9122M is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120, QPA9121 and QPA9122.
Typical Applications
- 5G mMIMO

8 Watt mMIMO 3.4 - 3.8 GHz RF Front End Reference Board
The reference design provides a complete solution for a RF front end (RFFE) for an 8W average output power mMIMO 5G application in band n78 (3.4-3.8GHz). The RFFE reference design provides a Tx/Rx solution from digital front end to antenna filter in a compact layout which can be directly implemented into an array. The design includes QPA9122M and QPB9362, directional coupler for DPD, and circulator.
