Claim Text:
1. An arrangement comprising: one or more power amplifiers, each power amplifier comprising a plurality of unit cells, the one or more power amplifiers adapted to amplify an input signal from a signal generator; an input power detector separate from the signal generator, the input power detector coupled with the signal generator and adapted to determine a power level of the input signal at an input of the one or more power amplifiers; and a control network separate from the signal generator and connected with the input power detector, the control network determining, upon receipt of the power level of the input signal, a number of unit cells to disable or enable and then send an individual control signal to each of the plurality of unit cells of each power amplifier to independently enable and/or disable the unit cells based on the determined number of unit cells and configured to adjust a tunable matching circuit operatively coupled to an output of one of the one or more power amplifiers and the control network based on the determined number of unit cells to disable or enable.
