Abstract : Wireless transmitters are affected by the reflection caused by an impedance mismatch between the power amplifier’s (PA) output and the antenna’s input. Isolators can lessen the output mismatch of the PA, but they add the bulk to the transmitter. A reflection-aware augmented PA modeling and Digital Predistortion (DPD) technique are proposed to reduce the influence of the dynamic varying reflection due to the output-load mismatch and the PA’s nonlinearities. This Augmented model includes a term that characterizes the mismatched effect. The proposed DPD with a single set of coefficients is robust and can mitigate the dynamic varying output-load mismatch with the PA nonlinearity.
