Definitions

  • the invention relates to a gas-tight, radio-frequency-permeable window arrangement between an input-side and an output-side coaxial line, in particular for traveling wave tubes.
  • a gas-tight, radio-frequency-permeable window arrangement in a coaxial line, in particular for traveling wave tubes in which a dielectric support is provided, through which the inner conductor of the coaxial line is passed with an outer diameter that is smaller than the normal one Inner conductor diameter in the coaxial line, but larger than the reduced inner conductor diameter required in the area of the support for adapting the wave resistance of the bushing to the wave resistance of the line.
  • this window arrangement is on both sides Support of the inner conductor is thickened conically in the direction of the support.
  • the dielectric support which can be made of ceramic material, for example, is disc-shaped, so that relatively high dielectric losses can occur in particular in high-performance tubes and the associated thermal load on the dielectric support can lead to their damage.
  • the invention has for its object to provide a gas-tight, radio-frequency-permeable window arrangement, which has a large bandwidth and which is mechanically and thermally stable.
  • a hollow cylinder made of dielectric material is provided between the input-side coaxial line and the output-side coaxial line, which surrounds the inner conductor of the input-side coaxial line and with its one end face on the outer conductor is connected on the input side coaxial line and with its other end face to a flange which is arranged between the inner conductors of the input and output side coaxial line.
  • a metallic compensation element which surrounds the inner conductor and the hollow cylinder, is preferably provided between the outer conductors of the coaxial line on the input and output sides; the latter expediently consists of beryllium oxide, aluminum oxide or boron nitride.
  • the dielectric load of the tubular window arrangement is tion is greatly reduced, so that in addition to BeD and BN, Al 2 0 3 can also be used as the material for the hollow cylinder.
  • the window arrangement is technologically simple to manufacture and can be designed for large pass bandwidths.
  • the arrangement according to the invention is mechanically and thermally stable and has relatively large sealing surfaces. Because of the small dimensions, thermal loads are not critical.
  • the window arrangement can be easily compensated for by cylindrical or conical turned parts.
  • the invention has the further advantage that the dielectric losses in the radio-frequency-permeable window are kept so low that high thermal or mechanical stress and thus cracking or leaking of the window is avoided even with high-performance traveling wave tubes.
  • the output power decoupled from the delay line of an amplifier (not shown) is fed to the window arrangement via the coaxial line 3, 4 on the input side.
  • the window arrangement consists of a hollow cylinder 1 made of dielectric material, one end face of which is soldered to the outer conductor 4 of the input-side coaxial line 3, 4. The other end face is soldered to the flange 5, which is between the two inner conductors 3, 3 'of the coaxial line 3, 3; 3 ', 4' is soldered.
  • a metallic compensation element 2 is preferably provided, which surrounds the inner conductors 3, 3 'and the hollow cylinder 2 made of dielectric material and, together with these elements, adapts the window arrangement via a broad frequency band to the coaxial connecting lines without reflection (r ⁇ 10 % from, for example, 2 GHz to 8 GHz).
  • the compensation element 2 can be stepped cylindrical (Fig. 1 and 3) or conical and consist of two parts 2, 2 '(Fig. 2).
