PURPOSE: To provide a structure of a resonator that eliminates the need for an expensive connector element for a mechanical and an electrical interface. CONSTITUTION: Some tongues 210, 220, 230, 240, 250; 310, 320, 330, 340 are machine-processed and placed on a printed circuit board 1 of a radio equipment side by side, the tongues are coated by a conductive material, the printed circuit board 1 is placed in a cage frame of the radio equipment, and the tongues are fitted to a frame in parallel with covers 12, 13 members made of a conductive material, between the covers 12, 13 and at an equal interval from the covers 12, 13 to form a high frequency filter. Thus, the filter is manufactured as above. |
