Abstract

This paper presents an electro-thermal behavioral advanced model of RF power amplifier including the load-pull effects for narrow band radar applications. An extension of nonlinear scattering functions is proposed for modeling large output impedance mismatches in the presence of high frequency memory and thermal effects. It combines a nonlinear scattering function block for the electrical response with a reduced order thermal model. The model implementation in an implicit system-level simulator will allow to achieve accurate and fast time-domain simulations to estimate temperature transients and signal distortions.
