FIELD: electronic equipment. ^ SUBSTANCE: slow-wave system of spiral type is suggested, which contains two hollow cylinders made of aluminium nitride with wall thickness of smaller hollow cylinder of 0.3/1 mm, and installed one inside another with the possibility of mutual contact provision along the whole surface of their contact, metal spiral made by laser beam on the external surface of smaller hollow cylinder, at that height of metal spiral section in the plane that is perpendicular to its length is provided as at least 0.05 mm. At that internal diameter of smaller hollow diameter, length of metal spiral, distance between its turns and external diameter of larger hollow cylinder are determined by wave length and value of maximum output power of electronic SHF appliance. ^ EFFECT: simplification of design, higher manufacturability, reliability, improvement of output parameters of electronic SHF appliance. ^ 1 dwg, 5 ex |
