Original Abstract Submitted
A Doherty amplifier is provided with a lumped-element combiner that includes a first capacitor and an inductor. Should the inductor be coupled between an output terminal of the main amplifier and an output node of the Doherty amplifier, the first capacitor couples between an output terminal of the auxiliary amplifier and the output node. Conversely, if the first capacitor is coupled between the output terminal of the main amplifier and the output node, then the inductor couples between the output terminal of the auxiliary amplifier and the output node. A current scaling ratio of the Doherty amplifier ranges from 0.4 to 0.6 to enhance the bandwidth.
