This Paper presents an energy-efficient asymmetrical Doherty amplifier based on the harmonic-tuned Class-F and Class- mode of operations. In addition, the design procedure of multi-resonant circuits tuned for second and third harmonics at the devise input/output are explored. The saturated Doherty architecture is designed by 10W GaN HEMT device from CREE at 3.6GHz and power added efficiencies of 50% at 8dB back-off and 55% at maximum output power of 43dBm have been achieved. This superposition performance has been confirmed by comparing the simulated results with that of conventional Doherty.
