Abstract
In the classical Doherty power amplifier (DPA) design, we usually use an equally divided power divider (branch line coupler) to separate the signal between the peak amplifier and carrier amplifier. Theoretically, the efficiency of the DPA can be improved by increasing the power ratio of the carrier amplifier to the peak amplifier. In this paper, we analyze the change of power added efficiency of the DPA when the signal is unequally divided rather than being equally divided.
