Abstract
Embodiments include different multi-port ring combiners which are configured to act as multi-output signal routers. One type of multi-port ring combiner includes input ports that are driven by pairs of outphasing signals. The multi-port ring combiner also includes multiple channels that are independently routed to a first output, to a second output, or to a third output, according to a phase relationship of the multi-port ring combiner. The multi-port ring combiner enables an outphasing signal combination which provides output port selection. The multi-port ring combiner may be a 4-port ring combiner, a 5-port ring combiner or a 6-port ring combiner.
