Abstract
A method, system, apparatus and article are described for optimizing transformer power combiners and for dynamically controlling power for outphasing power amplifiers. In some embodiments, for example, an apparatus may comprise one or more outphasing power amplifiers, one or more phase modulator modules coupled to and operative to dynamically control the one or more outphasing power amplifiers, and one or more power combiners coupled to and operative to combine outputs from the one or more outphasing power amplifiers, wherein the one or more power combiners comprise transformer power combiners arranged to combine outphasing signals using a primary inductor and differential signals using a secondary inductor. Other embodiments are described and claimed.
