This paper derives the theory and presents measurements of a new power amplifier based on the Doherty power amplifier topology. It is theoretically shown that the proposed amplifier can simultaneously provide high efficiency at both full output power and at output power back-off, over a much improved bandwidth compared to the conventional Doherty power amplifier. It is also shown that the proposed amplifier allows reconfiguration of the efficiency in power back-off without the need of tunable elements.A demonstrator circuit with individually controlled main and auxiliary amplifier input signals is designed to validate the theoretical findings. Measurements show state-of-the-art efficiency bandwidth with more than 49% drain efficiency at bot...
