  • Tapered-impedance distributed switching power amplifiers
    Patent number: 8310305
    Abstract: A distributed power amplifier may include a plurality of switching power amplifier sub-circuits, and a plurality of connection network sub-circuits, each of the plurality connection network sub-circuits having a characteristic impedance, wherein each of the plurality of connection network sub-circuits combines two or more of the plurality of switching power amplifier sub-circuits into a parallel or series configuration, wherein the plurality of switching power amplifier sub-circuits, the plurality of connection network sub-circuits and the characteristic impedance of each of the plurality of connection network sub-circuits are configured to present each of the plurality of switching power amplifier sub-circuits with a substantially equivalent load impedance.
