Abstract: A distributed amplifier arrangement (300) is provided in which a plurality of input signals (S1(t), . . . SN(t)) are separately controlled by a drive generator circuit (315) to produce modulation of a virtual load impedance at each amplifier stage. This permits each stage (302, 304, . . . 310) of the distributed amplifier (300) to operate at maximum efficiency by permitting the stage to produce an output voltage that approaches the supply voltage. As the output power is reduced, efficiency is maintained by systematically reducing the number of stages contributing to the output to the load.
