Abstract

PURPOSE: To increase withstand power capacity by insulating an impedance matching element installed on the output end of a helix type delayed wave circuit, from a metallic cylinder and its helix.
CONSTITUTION: A helix 3 which is retaied by a dielectric post 2 is arranged within a metallic cylinder 1 and thus constituted helix type delayed circuit is joined with an output waveguide 4. The match the impedance between the helix type delayed circuit and output waveguide, an impedance matching element 5 is put between the insulator 6 for the helix 3 and the insulator 7 for the metallic cylinder 1.
