ABSTRACT:
The disclosed waveguide branch separating filter can be modularly constructed of a basic frequency separating filter and of a filter expansion unit. Both the basic frequency separating filter as well as the filter expansion unit are composed of a reactively terminated (including short circuit) feeder waveguide to which the separating filters are coupled. The expansion of the basic frequency separating filter occurs in largely disturbance-free fashion during operation in that the reactive termination (including short circuit) thereof is mechanically replaced by the filter expansion unit and is electrically simulated during the refitting by a short-circuit plate or by short-circuit pins.
