Abstract (en)
[origin: DE102006061141A1] High frequency filter has a transfer behavior with a coupling impedance resonance with a blocking site at a specified frequency. The blocking site can be adjusted at the specified frequency by prescribing and/or selecting a defined capacitive and inductive coupling between two coaxial resonators (15) directly connected to a signal path (10). Preferred Features: n-coaxial resonators are coupled together on the signal path. The filter has band pass filters and a pair of coaxial resonators lying directly next to each other in the signal path have a trap circuit coupling per band pass filter.
