A manifold combiner for a plurality of radio frequency electromagnetic signals includes a first RF bandpass filter element with input and output ports and a first junction element, wherein the first junction element includes a first port connected to the first filter output port, a second port connected to a shorted stub element, and a third port functioning as an output. The signal path toward the stub appears as an open to the first filter. The combiner further includes at least one additional filter element and junction element, with the second port of the additional junction element fed from the output of the previous junction element. Interconnecting sections couple the respective elements. Dimensions of interconnecting sections are selected such that each filter element output sees a single path out of the manifold, through the output of the last junction element, with all other possible paths appearing as open circuits.
