| Zusammenfassung: | A dual mode filter, known in the art as a fourth order filter, has cylindrical coaxial input and output cavities that are connected through a coupling obstacle. The output of the dual mode filter is provided via a connector that carries a probe which extends within the end cavity. The input cavity supports a propagation therethrough of signals within a pass band of frequencies and within a parasitic band of frequencies. The diameter of the end cavity is smaller than the diameter of the input cavity, thereby causing the end cavity to suppress signals within the parasitic band. |
