摘要：
A digital, radio frequency (RF) power amplifier includes first and second RF digital to analog converters (RF DACs) and a combiner to combine output signals of the first and second RF DACs. In at least one embodiment, the digital RF power amplifier may be operated in any of a number of different operating modes by appropriately generating amplitude and phase input signals for the first and second RF DACs. A mode of operation may be selected for the digital RF power amplifier based, at least in part, on a desired average output power level of the power amplifier.
