Method and device for phase adjustment of dielectric filter

Abstract

Abstract PURPOSE:To easily make a phase adjustment by forming a through hole in a dielectric block where a conductive film is formed on its external surface and varying the phases of the input and output signals of a dielectric filter which is inserted into the through hole and guided to a conductor while varying the length and arrangement of a conductor part. CONSTITUTION:Conductive films are formed on the internal surfaces of through holes of the dielectric block 1 to form three penetrating conductive parts 2, and a conductive film 3 connected to the penetrating conductive parts 2 is formed on the external surface of the dielectric block. A three-stage dielectric filter FL is constituted where the three penetrating conductive parts 2 are formed. The through hole 5 is formed close to the right end of the dielectric block 1, a phase adjusting conductive film 6 is formed on the internal surface of the through hole 5 to form a part 7 where the conductive film is not present, and the phase adjusting conductive film 6 and conductive film 3 are insulated and separated from each other, so that the part where this phase adjusting conductive film 6 is provided operates as a phase adjusting device FS. Then, a flanged insulator 8 is fixed in the through hole 5 and a phase adjusting center conductor 9 is supported slidably in the through hole 5. A phase adjustment is made only by sliding the phase adjusting center conductor 9 upward and downward.
