  • POWER AMPLIFIER MATCHING CIRCUIT AND METHOD USING TUNABLE MEMS DEVICES
    Publication number: 20080094149
    Abstract: The present disclosure relates to a power amplifier circuit. In one example, the power amplifier circuit includes a power amplifier coupled to a variable load and a digitally tunable impedance matching network (TMN) positioned between the power amplifier and the variable load. The TMN includes at least one controllable capacitor having a maximum capacitance CT, where the controllable capacitor has a plurality of actuable capacitive elements having differing reactance values ranging from CT*20 to CT*2N, where N=>1.
