Abstract
In this paper, a power adaptive digital predistortion (DPD) model is proposed to linearize RF power amplifiers (PAs) operated in dynamic power transmissions. By employing the decomposed vector rotation (DVR) based nonlinear weighting technique to adjust the DPD coefficients dynamically, the distortion induced by the dynamic power operation can be effectively compensated. Experimental test results with a high power Gallium Nitride (GaN) Doherty PA confirm that higher linearization performance can be achieved by employing this model, compared to that using the existing approaches.
