PURPOSE:To attain ease of adjustment by forming a supporting base of a resonator into a polygonal shape so as to fix the resonator and the supporting base in an eccentric state thereby making the oscillating frequency and the oscillated power stable against vibration. CONSTITUTION:The upper face of the supporting base 2 is formed as an octagon, inserted to a recessed part of a case 5 and the periphery of a resonator Z is made in contact with one side of the octagon and the base 2 and the resonator Z are fitted while the centers of the resonator Z and the supporting base 2 are made eccentric. A distance (t) between a coupling strip line SL and the resonator Z takes sequentially five-stages of discrete values by turning the octal supporting base 2 at each 45 deg.. Thus, the distance (t) is decided with high accuracy, the frequency and power of oscillation are adjusted easily, the supporting base 2 is fitted to the recessed part of the case 5 and then is not moved to the right and left and the operation is made stable against vibration. |
