The invention relates to a high-performance ultra-high frequency tube, in which the maximum frequency energy is taken through a decoupling window that is perpendicular to the output waveguide Arranged longitudinal axis and is soldered vacuum-tight to the waveguide wall.

It is well known that waveguides are used to transmit the output power of high-performance ultra-high frequency tubes used when using the size of the power and the wavelength in question no longer allow a coaxial cable.

In order to effectively separate the vacuum part of the tube from the external circuit, the Necessity to attach a vacuum-tight partition inside the waveguide for electromagnetic Waves is permeable. This partition is usually referred to as a "window". This Window is made of any suitable insulating material such as ceramic, clay, glass, quartz.

In the case of the known tubes, the window is usually made with a metal frame of suitable construction hard soldered, which is then soldered into the waveguide with the window. Suitable means, such as B. Apertures, allow the correction of reflections that occur through the window and inside the waveguide its mounting frame. It is also known that the window directly on parts of the Solder the waveguide wall.

In the practical operation of the known arrangements, however, it has been found that these often Are subject to disturbances that lead to desoldering of the window.

The invention relates to a coupling-out window for high-performance ultra-high frequency tubes that is capable of is to endure the existing operating conditions without unsoldering.

In the case of a high-performance ultra-high frequency tube in which the high-frequency energy is transmitted through a coupling-out window is taken, which is arranged in an output waveguide perpendicular to its longitudinal axis and is soldered vacuum-tight to the waveguide wall, this goal is achieved according to the invention achieved that the output waveguide at the location of the decoupling window with one in the waveguide wall is provided bead-like indented, extending in the circumferential direction annular bead on which a side wall, the coupling window is soldered vacuum-tight.

The drawing is a section through a waveguide with a window construction according to the invention Is provided.

In the figure, the window consisting of a suitable insulating material is denoted by 1 and mounted inside a waveguide composed of sections 2 and 3. Either of the two Waveguide sections 2 and 3 are provided with a bead-like impression in the waveguide wall in the circumferential direction extending annular bead 4 and 5 provided at the opposite ends of sections 2 and 3 in any suitable manner, e.g. B. by pressing, beading or the like., Attached will. The window 1 lies between the annular beads 4 and 5, and the two waveguide sections are above it 2 and 3 soldered together with window 1 at 6.

Experiments as well as practical operation have shown that the annular beads 4 and 5 have the above-mentioned Eliminate faults completely.
