1. A method of combining power received from multiple input ports in a remote unit for a wireless communication system, comprising:
receiving input power from a plurality of external power paths in a wireless communication system into a plurality of input power ports each provided in a respective internal power path among a plurality of internal power paths;
providing a plurality of electrically isolated output powers based on the received input power from a respective input power port among the plurality of input power ports;
selectively controlling an amount of electrically isolated output power delivered in each respective internal power path, to a combined power node into a combined output power to be provided to at least one remote unit load, based on the measured available power from the input power port in the respective internal power path; and
measuring available power from each input power port among the plurality of input power ports in a respective internal power path among the plurality of internal power paths,
wherein selectively controlling the amount of electrically isolated output power comprises selectively controlling a plurality of switch circuits to selectively couple the electrically isolated output power in the respective internal power path, to the combined power node.
