Abstract (en)
[origin: EP1045470A2] The filter has coupled cavity resonators, of which at least two that are not in series for HF signals are connected for negative feedback via connectors inserted into each resonator. The cavity resonators are arranged so that at least the negatively coupled ones bound on each other and the conductor is in the form of a loop (21) protruding into one resonator that is connected through a slot (41) in the dividing wall (40) of the bounding resonator to a strut (22) in the other resonator.
