Abstract
Design of a harmonically tuned RF Power Amplifier (PA) with enhanced efficiency and
gain is presented in this paper. It makes use of a tri-band impedance transformer as a two-port
output network for facilitating concurrent optimum fundamental and harmonic impedances at the drain
terminal. The design is augmented by analytical formulations and analysis to identify the optimal
impedance matching scenario at the fundamental, second harmonic, and third harmonic. A thorough
analysis reveals that the proposed PA design scheme is very simple while maintaining the performance
obtained from the load-pull. A prototype operating at a frequency of 3.5 GHz is developed on RO5880
using 10W GaN HEMT. An excellent agreement between the measured and EM simulated results
validates the proposed design technique.
