IPC: H03B5/18
Filed: 1985-12-26
Abstract: PURPOSE:To facilitate adjusting work by arranging a movable plate slidably on the bottom part of a case and moving the movable body to adjust electromagnetic field coupling generated between any one of an oscillating transistor and a varactor diode and a dielectric resonator. CONSTITUTION:Strip lines 5, 6 are formed on a circuit board 8 in the forming direction of a step part 7 on the step part 7 side and the length of the parallel part of the line 6 is set up to the length capable of securing the maximum electric length l2 to be expected by the change or the like of the dielectric resonator 1 for instance. The varactor diode 3 is arranged on the position of electric length l2' from the starting point of the parallel part of the strip line 6. The electric length l2' is set up to an optional value within the range of lambda/2-lambda/4 of resonance wavelength lambda. Since a metal plate 9 can be moved in the step part forming direction within the range of a distance DELTAlambda, the metal plate 9 is moved to find out the position of an optimum coupling point l2 between the resonator 1 and the varactor diode 3 and the metal plate 9 is fixed on the position giving a coupling point k2.
