Abstract
PURPOSE: To improve the temperature characteristic by using a dielectric coaxial resonator whose polarity of the temperature characteristic is opposite to that of an oscillation circuit device which includes no resonators.
CONSTITUTION: After circuit constituting parts except resonators are attached to the circuit face of a circuit board 2, a reference resonator whose temperature characteristic is known is connected in the circuit to measure the temperature characteristic of the whole of the oscillation circuit device. The temperature characteristic of the oscillation circuit device which includes no resonators is discriminated in accordance with the result. Thereafter, a dielectric coaxial resonator 7 whose polarity of the temperature characteristic is opposite to that of the oscillation circuit device which includes no resonators is selected, and this resonator 7 is adhered in the conductive state so that the outer conductor is brought into face or line contact with an earth electrode 5, thereby producing the oscillation circuit device. Thus, the temperature characteristic of the resonator 7 acts to cancel the temperature characteristic of the circuit except resonators, and the temperature characteristic is improved.
