Microwave device using coaxial resonator

Abstract

Abstract PURPOSE: To obtain a small-size microwave device having a high mass-productivity, by using a flat plate type dielectric component which couples between the input and output terminals and then securing the electromagnetic coupling between the electrodes which are provided to the main plane of the dielectric component. CONSTITUTION: The TEM resonators 1a∼1f are fitted into the holes 17∼22 within the main case 16, and the external conductors 3a∼3f are fixed to secure an electric conduction to the case 16. The dielectric component such as the ceramic plate 24 is put on the stage part 23 provided to the inner wall of the case 16. The electrode films 25a∼25f are formed on the main plane of the plate 24 along with holes 26a∼ 26f piercing through the plate 24 drilled through the films 25a∼25f, respectively. Then the terminals 8a∼8f of the resonators 1a∼1f are pierced through the holes 26a∼26f each to be connected to electrodes 25a∼25f. The signal transmission among the resonators or the signal application to the resonators and the signal extraction out of the resonators are carried out through the electrostatic capacity coupling. In such way, a small-size microwave device for the filter or the like can be obtained with a high mass-productivity. COPYRIGHT: (C)1981,JPO&Japio
