Abstract: In order to deepen students understanding of the operating principle of high frequency class C amplifier,the mature experimental program is proposed after three years of experimental teaching.Firstly,the design of the circuit schematic diagram and the selection of components selection are designed specifically.Then,the impact on the operating state is researched through actual testing when the excitation voltage,load,supply voltage variations changed.Moreover the experimental results are analyzed with the theory.Finally,the problems encountered in the experiment are analyzed and discussed.The experimental results show that the project clearly reproduced the work process of the class C power amplifier,and the favorable teaching effect was obtained.It may be helpful for the other universities to open the class C power amplifier experiments.
