Abstract :
In this study an improved behavioral modeling including even order terms is proposed to model asymmetric IMD components observed in the multi-tone excitation of nonlinear amplifiers. Only odd order model (OOM) and even order introduced model (EOM), proposed model, are constructed and compared for a sample amplifier. It is showed that introducing even order term is improved the model validity range and accuracy in addition to the decrease model polinomial order.
