Abstract

A system includes more than one subsystem, each subsystem operating within a different subsystem frequency range, the subsystems comprising a circulator having three or more circulator ports and a direction of circulation, the circulator operating within a specific frequency range of the subsystem frequency range, and a filter, such as a bandpass filter, connected to at least one of the circulator ports. The filters each define a subsystem port and operate within the specific frequency range. Each subsystem port has a port index determined by the direction of circulation of the circulator within the subsystem. Each subsystem port has a specific port index that is connected to a common port having the specific port index. At least one of the circulator ports may be terminated to a matched load. Each subsystem circulator may comprise at least three circulator ports, with a filter connected to each of the circulator ports.
