  • Doherty amplifier having compact output matching and combining networks
    Patent number: 8653889
    Abstract: A Doherty amplifier having a main amplifier branch and one or more peak amplifier branches, where the functionality and structure of the cascade of the main output matching network, the main offset line, and the quarter-wave transformer of the main amplifier branch of a conventional Doherty amplifier are subsumed into the main output matching network of the main amplifier branch, and the functionality and structure of each cascade of the peak output matching network and the peak offset line of each peak amplifier branch of a conventional Doherty amplifier are subsumed into the peak output matching network of the corresponding peak amplifier branch. Furthermore, the output quarter-wave transformer can be replaced by a wideband node matching network that does not have to perform frequency inversion.
