| Abstract: | An improved design method of class-E wide band-gap power amplifier with input harmonic suppression is proposed,by which the input harmonic power can be used and the power-added efficiency(PAE) can be improved.The work principle of the class-E power amplifier is analyzed,and using the wide band-gap device,the improved class-E power amplifier is designed by the software ADS.Measurement results of the actual amplifier circuit show that because of the improvement of input harmonic suppression,the output power of the power amplifier in 1.1~1.3 GHz keeps above 10 W and the PAE reaches to 79.6%.The capacity of the improved class-E power amplifier is obviously superior to the conventional one. |
