N2 - This paper will briefly review aspects of memoryless nonlinear power amplifier behavioural models in the context of the more popular ones - the complex power series expansion, the Saleh model, and the Bessel-Fourier (B-F) model. Other models considered will be the Fourier model, the Hetrakul & Taylor model and the Berman & Mahle model. Static envelope characteristics, i.e., static AM-AM and/or AM-PM characteristics, are taken as the basis for defining a behavioural model as memoryless. Some new insights and new developments are presented including a new modified Saleh model - evolved to overcome some particular weaknesses of the Saleh model - and considerations on applying the B-F model and its linkage to the Fourier model. Some comparative considerations among models will be presented, through their application to modelling an LDMOS amplifier amplifying a WCDMA signal.
