| 摘要 |
The invention relates to a device for mechanically adjusting a frequency of dielectric resonators (22) which are disposed on an electric conductor substrate (24). A mechanical chamber (20) is arranged above the substrate (24) for field definition. A cover part (10) of the chamber (20) contains a recess, which is located above the dielectric resonator (22), wherein the deformation area (5) of a conductive deformable deformation wafer (1) fixed to the cover part (10) is arranged. Preferably, the deformation wafer (1) is a piece of sheet metal with retaining clips on the end thereof. Said extensions are introduced into specially provided openings of the cover part (10) and bent, when the deformation wafer is fixed. In order to adjust the frequency, the distance between the conductive deformation wafer (1) and the dielectric resonator (22) is reduced accordingly by simply deforming the wafer (1). Deformation can be carried out either manually or automatically by means of a die. The stable cover part (10) is not deformed, along with the outer walls of the chamber (20) which are integrated as elements. The invention can be used for dielectrically coupled resonator filters (DR filters) as well as for dialectic resonator oscillators (DRO). |
