| Abstract: | In order to enable students to understand the effect of nonlinearities of power amplifiers on transmitted signals, the sharing linearization platform for power amplifiers can be introduced to experimental teaching in the course of radio frequency(RF) circuit design, transforming the abstract nonlinear theory and linearization approaches into visualized demonstrations, so as to improve the students’ enthusiasm and teaching effectiveness. It elaborates the predistortion module, linearization system, construction of sharing platform and measurement example, which is helpful for students to understand and master the practical application of RF transmission system. |
