PURPOSE:To enable fine adjustment of the coupling coefficient and oscillating frequency, by fitting the dielectric device of the microwave oscillator using it as the rsonance element to the mobile device, and changing the relative location with the strip line. CONSTITUTION:The microstrip line 2 is provided at the lower surface 12 of the shield case 1 via the dielectric substance layer 21, the microwave oscillating element 3 is connected to one end of the line 2, and the dielectric resonator 4 is provided near the line 2. The oscillator 4 is almost disc shape and fixed to the mobile device 5 via the dielectric substance 41. This mobile device 5 is constituted with the vertical mobile section 6 and the horizontal mobile section 7. The fine adjustment of the oscillating frequency can be made by rotating the screw shaft 62 of the vertical mobile section 6 for a prescribed number. The degree of coupling can be adjusted by sliding the horizontal mobile part 7 along the long hole 13 provided on the chassis 1. After the end of adjustment, the lock nuts 63, 75 are tightened and the position is fixed. |
