| 摘 要： | 为了对F类与逆F类功率放大器的效率进行研究,首先从理论方面对两种放大器工作模式各自的效率进行了计算。通过计算可以看出,在相同的输出功率下,因为晶体管导通内阻的存在,逆F类功率放大器的效率优于F类功率放大器。再通过软件仿真设计F类和逆F类功率放大器,在相同的输出功率下,逆F类功率放大器的最高漏极效率为91.8%,F类功率...

| Abstract: | The research aims at analyzing the efficiency differences between class-F and inverse class-F power amplifier.First,the efficiency of each amplifier was calculated on the theoretical basis.According to the formula,the inverse class-F amplifier had better efficiency than that of class-F amplifiers at identical output power level,owing to the on-resistance of the transistor.Then the two amplifiers were designed through software simulation.At identical output power level,inverse class-F power amplifier's maxim... |
