The QPB3810 is an integrated 2-stage GaN Doherty Power Amplifier Module with a Bias Controller designed for m-MIMO applications with 8W RMS at the device output.
The integrated bias controller is factory programmed to set optimal bias points of the Doherty power amplifier module. The controller includes a temperature sensor and adjusts bias over temperature. The controller also includes an enable pin for fast TDD switching.
The QPB3810 is housed in a compact 12 mm x 8 mm SMT Package. This is much smaller footprint than traditional discrete component solution and requires minimal external circuitry.

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, QPB3810, QPB9362, directional coupler for DPD, and circulator.
