| 摘要 |
The invention relates to a high frequency filter of coaxial construction, comprising an outer conductor housing (1) with a housing base (1b) and a housing wall (1a), whereby several resonators (R1, R2, R3, R4) are embodied in the outer conductor housing (1), each comprising an inner conductor tube (2), electrically-coupled to the housing base (1b). At least one part of adjacent resonators (R1, R2, R3, R4) are electrically-coupled to each other by means of at least one coupling opening (3, 4, 5) in the outer conductor housing (1). Said filter is characterised in that one or more recesses (9) are embodied in the housing base (1b), between at least one part of the inner conductor tube (2) of adjacent resonators (R1, R2, R3, R4). |
