This article introduces the application of three-parameter equivalent circuit models of transistors in various circuits of wireless communication systems. It mainly introduces the equivalent circuit of mixed πparameter, h parameter and Y parameter. Based on the three parameters, the transistor model is established. According to the circuit model, the parameters of the amplifier are obtained. The circuit model constructed by the parametric equivalent circuit is simple and convenient to calculate. It provides a good analysis basis for the analysis of the circuits at various levels in the wireless communication system and provides convenient conditions for the study of signal transmission and processing in the wireless communication system.
