HIGH FREQUENCY OSCILLATING CIRCUIT

摘要

PURPOSE:To attain mass production of circuit having a desired characteristic by inserting a coaxial resonator into a groove provided to a case holding a printed board and fitting the coaxial resonator to the case by a fixing screw or the like so as to attain ease of replacement of components and the control of oscillating frequency. CONSTITUTION:The printed board 1 and the coaxial resonator 2 are constituted separately. The coaxial resonator 2 is inserted into the groove 4a of the shape of resonator provided in the case 4, a center conductor 3 of the resonator 2 is inserted into an opening 6 provided on the board 1, and after the position or the like of the coaxial resonator 2 is adjusted so that a desired oscillating frequency and characteristic is obtained, the coaxial resonator 2 is fixed by the fixing screw 5 and the board 1 and the center conductor 3 are fixed by a solder 6 finally. The resonator 2 is replaced freely through the constitution in this way, the oscillating frequency and characteristic are controlled easily and a desired characteristic is mass-produced.
