Web31 de jul. de 2024 · Since the general Doherty power amplifiers have another peak efficiency at the 6 dB output power back-off (OPBO), asymmetric Doherty power amplifiers (ADPAs), where the output power capacity of the peaking amplifier is larger than that of the carrier amplifier, have been proposed for a higher efficiency for larger OPBO [–]. WebIn this paper, a different dual-band asymmetric Doherty power amplifier (ADPA) with a novel dual-band bandpass filter (DBBPF) with quad-section stepped impedance resonators (SIRs) is presented. This specific DBBPF rejects the annoying frequencies of the second and third harmonics in the dual-band and contributes considerably to performance …
