ABSTRACT:
A gas-tight, high-frequency permeable window arrangement is provided between the input and output sides of a coaxial line, particularly for traveling wave tubes. The dielectric losses, particularly given high-performance tubes, are held so low that too high a thermal load and, thus, a fracture or, respectively, loss of seal of the window arrangement is avoided. For this purpose, a ceramic hollow cylinder is provided between the coaxial line of the input side and the coaxial line of the output side, the ceramic hollow cylinders surrounding the inner conductor of the coaxial line of the input side in the area of its transition to the coaxial line of the output side as a continuation of the outer conductor of the coaxial line of the input side.
