Abstract:
1. A distributed power amplifier, comprising: 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 at least two of the plurality of switching power amplifier sub-circuits into a substantially series configuration such that each of the plurality of switching power amplifier sub-circuits is presented with a substantially equivalent current waveform, 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 such that each of the plurality of switching power amplifier sub-circuits has a substantially equivalent drain voltage waveform.
