摘 要:This paper presents a new topology to implement Class F power amplifier for eliminating the on-resistance (R_(ON))*** time-domain and frequency-domain voltage and current waveforms for Class F amplifier are ana- lyzed using Fourier series analysis *** the on-resistance effect,the formulas of the efficiency,output power,dc power dissipation,and fundamental load impedance are given from ideal current and voltage *** experimental verification,we designed and implemented a Class F power amplifier,which operates at 850 MHz using MGaAs/GaAs Heterostructure FET(HFET)device,and analyzed the measurement *** results show that the maximum PAE of 67% can be achieved at 28 dBm output power level.
