    (Institute of Electrical and Electronics Engineers Inc., 2023) Manoj, H.; Prasad Gupta, M.S.; Deepak Naik, J.; Gorre, P.; Kumar, S.
    This paper presents a performance analysis of the high efficiency broadband Class F Power Amplifier using even-odd mode matching techniques in Gallium Nitride HEMT Technology for Sub-6-GHz 5G Application. The proposed design circuit consists of broadband input matching network which provides a wideband operation by canceling higher harmonics, high efficiency Class F main amplifier, and series shunt network to enhance the bandwidth. The proposed PA with built-in techniques achieves a fractional impedance bandwidth of 110% in frequency range 2 GHz to 5GHz. The GaN HEMT PA is analyzed and simulated using Keysight's Advanced Design System simulator. A maximum drain efficiency of 78.82% is achieved with a power gain ranging from 10~14 dBm. In addition, an output power > 40 dBm is achieved with the proposed design with drain voltage of 28 V. © 2023 IEEE.
