摘要：An EMP-eliminator is to be created which is simultaneously applicable formultiple frequency bands and highest frequencies and at the same time allows

transmission of AC/DC supply voltages. For this purpose a casing (20) set in an outer line(10) is provided as well as a line (24) connected in an electrically conductive manner to aninner line of a coaxial line (30). The line (24) is connected in an electrically conductivemanner with the equipment casing (20) or its face side via a gas filled overvoltagesuppressor (28). The gas eliminator (28) is set into a threaded cover and thus can beexchanged. Between the equipment casing (20) and the line (24) several bushes (25, 26)connected electrically to the line are provided. The length of the line (24) corresponds tothe &lgr;/4 length of the lowest transmitted frequency band. Several serially connectedresonant cavities result which are matched in their length to different midband

frequencies. With this kind of serially connected resonant cavities it is easily possible totransmit several frequency bands and thus protect end apparatuses from interferencecurrent impulses. The capacitance of the overvoltage suppressor (28) is decoupled by theline (24) and the bushes. (25,26) to such a degree that use up to 18 GHz is possible.
