Patent abstract

A power amplifier architecture includes a plurality of non-linear optically driven power amplifier modules. The plurality of non-linear optically driven power amplifier modules are selectively connectable utilizing a programmable algorithm for combining at least two modules of the plurality of non-linear optically driven power amplifier modules in a time sequence yielding a piecewise approximation of a continuous waveform. The power amplifier architecture further includes at least one RF drive selectively connected to at least one of the plurality of non-linear optically driven power amplifier modules via an optical signal link generating a separate drive signal for each of the plurality of non-linear optically driven power amplifier modules.
