Abstract
A gas-tight, high-frequency permeable window arrangement in a coaxial line, particularly for traveling wave tubes, has a large pass band width as well as being mechanically and thermally stable. For this purpose, a hollow cylinder of dielectric material is provided between the coaxial line on the input side and the coaxial line on the output side, the hollow cylinder surrounding the inner conductor of the coaxial line on the input side and being connected with its one end face to the outer conductor of the coaxial line on the input side and being connected with its other end face to a flange which is arranged between the inner conductors of the coaxial lines of the input and output sides. A window arrangement constructed in accordance with the present invention is particularly suitable for employment in radio link traveling wave tubes.
