PURPOSE:To attain ease of minute adjustment of a frequency by providing a frequency minute adjusting screw to a metallic cylinder fixing a dielectric resonator. CONSTITUTION:The MIC oscillator is constituted by a microstrip line 3 and the dielectric resonator 5 arranged on a metallic substrate 1. The dielectric resonator 5 is fixed to the metallic cylinder 12 via a dielectric spacer 11. The metallic cylinder 12 is fixed to a metallic case 7 by using a conductive adhesives 14. The frequency minute adjusting screw 13 is provided to the center axis of the metallic cylinder 12 and the minute adjustment of the frequency is conducted by using the adjusting screw 13. Further, the output power, prescribed load Q and the frequency are adjusted coarsely by utilizing a long hole 72 formed to the metallic case 7 so as to move and adjust the case 7 in the direction of C D. |
