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. For the transmit chain the reference design features the QPA9122M as a wideband high linearity pre-driver and the QPB3810 as a highly efficient GaN final stage power amplifier module. The transmit chain also includes a directional coupler for DPD observation path as well as a circulator. For the receive chain the reference design includes the low noise QPB9362 switch LNA.
