Abstract (en)
The invention relates to a Filter (FL1) for radio frequency, RF, signals comprising a first cavity resonator (RC2), a second cavity resonator (RC5), separating means (ISP1) separating said first cavity resonator (RC2) and said second cavity resonator (RC5), and coupling means (100) for capacitively coupling said first cavity resonator (RC2) and said second cavity resonator (RC5), wherein said coupling means (100) comprise a connecting element (104) protruding through an opening (OP1) in said separating means (ISP1), a first coupling element (102a) that is arranged in said first cavity resonator (RC2) and that is connected to said connecting element (104), a second coupling element (102b) that is arranged in said second cavity resonator (RC5) and that is connected to said connecting element (104), wherein at least one of said coupling elements (102a, 102b) is movably attached to said connecting element (104) and/or said connecting element (104) is rotatably attached to said separating means (ISP1).
