Abstract (en)

[origin: DE19523869A1] The invention addresses the problem of designing a band-pass filter for a waveguide which can also act as a blocking filter for the suppression of specific interference frequencies. This problem is solved by an arrangement in which a waveguide screen is provided, in addition to a centrally positioned aperture (3), with two other identical apertures (4) which are set, with respect to the natural resonance, for an unwanted interference frequency f(ind S1) and arranged symmetrically about the central aperture (3). The invention can be used to prevent waveguide devices from infringing statutory frequency specifications and for the suppression of interference frequencies.
