A 9 dB back‐off dual‐band asymmetric Doherty power amplifier using dual peaking amplifiers for reactance compensation

Abstract: This paper proposes a dual‐band asymmetric Doherty power amplifier (ADPA) with 9 dB power back‐off range using dual parallel peaking amplifiers to realize reactance compensation for wideband operation at two frequency bands. To achieve dual‐band amplification, the specific phase delays of the carrier and peaking output matching networks (OMNs) required on the two target frequency bands were determined using the phase delay period repeatability principle combined with the Doherty impedance transformation first.… Show more
