Abstract(in English) | We have developed a microwave inverse class-F GaN HEMT amplifier using a harmonic treatment circuit constructed with lumped circuit elements. The harmonic treatment circuit consists of a series reactance network having zero impedance at the odd order harmonic frequencies and poles at the even order higher harmonic frequencies as well as a shunt reactance network having zero impedance at the odd order harmonic frequencies. The harmonic treatment circuit can be considered more than 4th order higher harmonic frequencies. A fabricated AlGaN/GaN HEMT inverse class-F amplifier considering up to 4th order higher harmonics delivered a power-added efficiency of 76.3% and a drain efficiency of 78.3% at 879MHz. |
