Claim of US Patent No. 10,142,136

1. An apparatus for providing self-consistent outphasing signal separation, the apparatus comprising:a receiver configured to receive a variable-envelope signal;
an outphasing separator comprising at least one digital component configured to split the received variable-envelope signal into first and second, constant-envelope signals, wherein splitting the received variable-envelope signal comprises applying functions using consistent phase;
a first analog component chain comprising one or more analog electrical components configured to receive and process the first, constant-envelope signal;
a second analog component chain comprising one or more analog electrical components configured to receive and process the second consistent phase, constant-envelope signal;
an analog combiner configured to combine the processed first and second constant-envelope signals for transmission to one or more other entities or systems; and
first and second linear pre-equalizers configured to receive the first and second constant-envelope signals and apply pre-equalization such that, when applied, signal distortions are summed out at the output of the analog combiner.
