Abstract:
Embodiments relate to outphasing amplifiers and amplification. One example system includes a signal splitter configured to receive an input signal and output a plurality of signals, wherein the signal splitter shifts each of the plurality of signals by a distinct phase based at least in part on a power of the input signal; a plurality of power amplifiers (PAs), each configured to amplify a distinct signal of the plurality of signals to generate a distinct amplified signal; a plurality of input matching networks, each coupled to a distinct PA of the plurality of PAs and configured to transform an input impedance of the coupled PA to an outphasing load condition based on the distinct signal the coupled PA is configured to amplify; and a combiner configured to combine the plurality of distinct amplified signals to generate an amplified input signal.
