逆F类放大器漏极电压波形研究

Abstract

Abstract:

Inverse Class F power amplifiers improve efficiency of microwave circuit by adjusting waveform of drain voltage and current.For a better understanding of the nature,the waveform of drain voltage and current are analyzed theoretically and simulated.The result shows that if only the second and third harmonics are considered with the second harmonic and fundamental wave voltage ratio k=1/4,the drain voltage waveform is the most flat and the drain voltage tends to be a half-sine.Finally,an inverse class F power amplifier with k=0.271 is designed and the actual circuit is manufactured,with a peak power-added efficiency of 71% and an output power of 36.33 dBm.
