A RF-filter comprising resonator walls (21-26) delimiting a cavity (11) and at least a first and a second resonator (31, 32). A coupling adjuster (611, 621) for adjusting the electromagnetic coupling is arranged between said first and second resonators (31, 32). The coupling adjuster (611, 621) includes an elongated body (611, 624) arranged to be rotatable around an axis located in a plane between the first and the second resonator (31, 32). The coupling adjuster and a supporting wall (612, 622) portion are integral with an internal wall (61, 62) arranged between two resonators. |
