Abstract:
A linear power amplifier system comprising:an input; a splitter, said splitter including a splitter input and a plurality of splitter outputs; a plurality of linear power amplifier modules, each amplifier module including an amplifier input and an amplifier output, each amplifier input coupled to at least one splitter output; a combiner, said combiner including a plurality of combiner inputs and a combiner output, each combiner input coupled to at least one amplifier output; a control functionality, said control functionality including at least one control functionality input and a plurality of control functionality outputs; wherein said input is coupled to said splitter input; and wherein a first control-functionality output is coupled to at least one amplifier module, a second control functionality output is coupled to said splitter, and a third control functionality output is coupled to said combiner and wherein said control functionality monitors said at least one control functionality input and in response to detecting a predetermined condition, the control functionality: controls an operation state of said at least one amplifier module; controls how many splitter outputs are generated from said splitter input; and controls how many combiner inputs are used to generate said combiner output.
