Conventional power amplifier systems trade-off efficiency for linearity due to transistor operation limitations. The Smart Power Amplifier architecture improves RF Power Amplifier linearity without compromising efficiency. This novel invention generates and utilizes specialized outphased signals that can be used in outphasing RF power amplifiers in order to amplify the input signal without suffering from the nonlinearities and inefficiencies associated with conventional power amplifiers. Using this proposed technique, designers and developers can generate variable number of outphased signals on the fly with minimal processing and memory footprints. The proposed architecture for constructing and combining a variable number of constant amplitude outphased signals results in both highly linear and significantly efficient power amplification system. The complexities of both constructing and combining the decomposed signals are significantly reduced due to the fact that all of the decomposed signals except only two of them are actually scaled versions of the input signal.
