  • Method and apparatus for phase balancing of amplifier modules
    Patent number: 7230478
    Abstract: In a method and apparatus for of balancing the phases of a plurality of amplifier modules so as to maximize the combined power output of the amplifier modules an amplifier module is selected as a reference module with a fixed phase in a first step. In a second and subsequent steps, the phase of each of the other amplifier modules is each adjusted relative to the reference module, such that the combined power output from the respective individual amplifier module and the reference module is minimized. Finally, the phase of the reference module is rotated by 180°.
