Abstract (en)

[origin: US6340922B1] A band-pass filter for a waveguide, which additionally serves as a blocking filter for the concerted suppression of interference frequencies. In addition to a centrally arranged aperture (3), a waveguide aperture has two identically designed apertures (4), which are laid out for natural resonance for an interference frequency f (ind S1) to be blocked by the waveguide filter, and are arranged symmetrical to the central aperture opening (3). In waveguide devices, the invention is used to meet the statutory frequency specifications and simultaneously suppress interference frequencies.
