Abstract
An apparatus relates generally to multiband power modulation. In such an apparatus, there is a first power supply and a second power supply. The first power supply and the second power supply are each narrow-banded. A digital predistorter is coupled to provide separate bands of a modulation signal for respective input of a first band of the bands to the first power supply and a second band of the bands to the second power supply. The first power supply generates a first power at a first center frequency. The second power supply generates a second power at least at a second center frequency spaced apart from the first center frequency for a wide-band configuration. The second power output from the second power supply is coupled to the first power output from the first power supply to provide a multiband power modulation output.
