ABSTRACT:
A T-shaped rectangular waveguide branching filter includes an electrically conductive projection or protrusion of approximately triangular cross section which is formed at a predetermined portion within the branching filter for preliminary impedance matching of a predetermined accuracy as observed from each of the input/output ports of the branching filter, and an electrically conductive rod which may be selectively advanced toward or retracted from the first input/output port and extends through the electrically conductive protrusion of triangular cross section so that, by selectively advancing or retracting the conductive rod, a particular impedance match corresponding to each of the input/output ports as observed from any one of the input/output ports may be achieved for efficiently deriving the signal applied to one of the input/output ports from either one of the other input/output ports.
