| 摘要 |
The invention relates to a high-frequency filter (1) of cavity design comprising at least two resonators (41, 51, 61, 71) each having a resonator inner conductor (41b, 51b, 61b, 71b), wherein the at least two resonators (41, 51, 61, 71) each form a filter path (4, 5, 6, 7) or are a constituent part of such a filter path (4, 5, 6, 7). Furthermore, the high-frequency filter (1) comprises at least one interconnecting resonator (2), which has an interconnecting resonator inner conductor (3), wherein the interconnecting resonator inner conductor (3) is connected electrically to a housing base and extends in the axial direction from the housing base in the direction of the housing cover. The interconnecting resonator (2) is coupled to the at least two resonators (41, 51, 61, 71) and is fed at least one further signal path (11). An outer surface (10) of the interconnecting resonator inner conductor (3) is larger than each outer surface (41c, 51c, 61c, 71c) of all the resonator inner conductors (41, 51,61, 71) which are coupled directly to the interconnecting resonator inner conductor (3). |
