Abstract

A new generic modified Saleh (MS) model for use in memoryless nonlinear power amplifier (PA) behavioural modelling is proposed. The model was evolved primarily to overcome some particular weaknesses in the original Saleh model when handling the polar AM-PM envelope modelling. From it new twoparameter MS polar models are derived. By modelling a nearmemoryless LDMOS PA amplifying a WCDMA signal, evidence of the improvement in modelling accuracy and performance of the MS over the original Saleh for both polar and quadrature models is provided.
