Filtering Doherty power amplifier [PDF]
IET Microwaves, Antennas & Propagation, 2020 At present, it is a trend in wireless communication to integrate conventional separate components into a single one for further miniaturisation and whole performance optimisation. In this study, a novel filtering Doherty power amplifier topology is proposed, which incorporates a bandpass power divider for power division.
