Patent ID: 10181866

Abstract:
An outphasing transmitter includes a combiner, a decomposition block, first and second power amplifiers, and antennas in a phased array antenna panel. The combiner combines a plurality of beamforming signals into a composite input signal. The decomposition block decomposes the composite input signal into first and second decomposed radio frequency (RF) signals coupled to the first and second power amplifiers. Non-overlapping sub-arrays of the antennas may be uniquely associated with the first and second power amplifiers. Alternatively, groups of interleaved antenna rows may be uniquely associated with the first and second power amplifiers. Alternatively, random pluralities of the antennas may be randomly hard-wired to the first and second power amplifiers. Alternatively, pluralities of the antennas may be dynamically and selectably assigned to the first and second power amplifiers. The phased array antenna panel forms a plurality of RF beams corresponding to the plurality of RF beamforming signals.
