本文指出E类功率放大器的最高工作频率取决于晶体管的占空比。在输出功率、直流电源电压和并联电容固定的情况下,零电压开关和零导数开关条件下,最大工作频率随着占空比的减小而增大。
This paper shows that the maximum operating frequency of the class-E power amplifier depends on the transistor duty ratio. The maximum operating frequency increases as the duty ratio decreases under zero-voltage switching and zero-derivative switching conditions at fixed values of the output power, dc supply voltage, and shunt capacitance.
