Claim of US Patent No. 9,954,706

1. A spatial combiner device, the spatial combiner device comprising:a plurality of RF input connectors configured to receive input signals;
constant envelope circuitry coupled to one or more of the RF input connectors, wherein the constant envelope circuitry is configured to convert a variable envelope signal into two or more constant envelope signals, but wherein at least one of the RF input connectors is not coupled to the constant envelope circuitry;
a plurality of power amplifier circuits, wherein each of the power amplifier circuits in the plurality of power amplifier circuits is coupled to one of the input connectors in the plurality of RF input connectors;
a plurality of spatial radiators, wherein each of the spatial radiators is coupled to one of the power amplifier circuits in the plurality of power amplifier circuits;
a spatial combiner aperture, wherein each of the spatial radiators is spatially coupled to the spatial combiner aperture such that each of the spatial radiators is configured to emit signals that can be received by the spatial combiner aperture, such that the spatial combiner aperture is configured to combine constant envelope signals derived from constant envelope signals input into one or more of the RF input connectors and constant envelope signals derived from variable envelope signals input into the constant envelope circuitry; and
an output RF connector coupled to the spatial combiner aperture, the output RF connector configured to provide an output signal, wherein the output signal comprises a combined signal comprising a combination of amplified signals.
