High Efficiency Frequency Tunable Inverse Class-E Amplifier in VHF Band
Abstract This paper proposes the use of an inverse class-E amplifier with a tunable parallel resonator at the output port in order to obtain a high power-added efficiency (PAE) and output power in a wide frequency range. The tunable resonator circuit has a constant Q factor in the operating frequency range, and since the circuit has a varactor diode, the inductor and capacitor values of the resonator can be changed. Further, the inductance value for zero-current switching (ZCS) is implemented a lumped element and the capacitance value is made a distributed element for phase compensation. The inverse class-E amplifier can deliver an output power of 25dBm and can achieve a maximum a PAE of 75% in the frequency range 65-120MHz.
