Claim of US Patent No. 10,236,839

1. A method of spatially combining signals, the method comprising:receiving a plurality of RF input signals at a plurality of RF input connectors, wherein at least one of the RF input signals is a variable envelope signal;
converting the at least one variable envelope signal, received at a first RF input connector in the plurality of RF input connectors, into two or more constant envelope outphased signals;
amplifying the two or more outphased constant envelope signals;
radiating the amplified outphased constant envelope signals;
amplifying at least one other RF input signal received at a second RF input connector in the plurality of RF input connectors;
radiating the amplified at least one other RF input signal;
at a spatial combiner aperture,
spatially combining the radiated amplified outphased constant envelope signals and the radiated amplified at least one other RF input signal to create a combined signal; and outputting the combined signal onto an output RF connector.
