Abstract:
A consecutive Doherty amplifier is disclosed. The Doherty amplifier includes a carrier amplifier, a power splitter, a peak amplifier, and a phase compensator. The carrier amplifier receives a radio frequency signal with interposing any signal splitters. The power splitter splits an output of the carrier amplifier into first and second split signals. The phase compensator transfers the second split signal to the peak amplifier. The first split signal is combined with the output of the peak amplifier.
