Résumé

In this paper, two different models for the baseband digital predistortion of a GaN power amplifier have been applied: the widely-used Memory Polynomial (MP) model and the recently proposed Behavioral Model with Dynamic Deviation Reduction for Wideband Amplifiers (DVBW). Their performance has been experimentally compared in terms of Adjacent Channel Power Ratio, Error Vector Magnitude and Power Added Efficiency. The DVBW model outperformed in general the MP model, exhibiting also good generalization characteristics.
