Patent ID: 7751902

Claim:
A wide dynamic range power amplifier comprising: a first output driver adapted to receive a periodic signal and a power signal, and further adapted to generate a first push-pull output comprising an amplified replica of the periodic signal; a level and phase processor adapted to receive the periodic signal and a control signal, wherein the level and phase processor is adapted to generate a phase shifted signal substantially representing a 180 degree phase shifted version of the periodic signal when the control signal indicates a high power mode, and wherein the level and phase processor is adapted to generate the phase shifted signal set to zero when the control signal indicates a low power mode; a second output driver adapted to receive the phase shifted signal and generate a second push-pull output comprising an amplified replica of the phase shifted signal; a first matching network and a primary coil residing in-series between the first push-pull output and the second push-pull output; and a secondary coil and a second matching network adapted to cooperate with the primary coil to generate an output signal.
