Abstract
Certain aspects of the present disclosure provide methods and apparatus for operating a power amplifier. In one example, the apparatus includes a power amplifier configured to amplify an input signal having a frequency to produce a radio frequency (RF) output signal at an output and a harmonic tuning circuit coupled between a power supply and the power amplifier output, the harmonic tuning circuit configured to reduce a current or voltage provided to the power amplifier via a resonance at one or more harmonics of the frequency of the input signal.
