| 摘要 |
The invention relates to a device for the fine adjustment of a resonant microstrip-line formed on an insulating substrate (2), tuned by a varicap diode (7,8) which makes it possible to adjust the shape of the curve representing the tuning frequency of the strip line as a function of the direct voltage controlling the diode. According to the invention, one or more blind holes are provided in the surface of the substrate opposite the strip line, under the latter, and a mechanical part (15) with one or more threaded holes into which cylinders are screwed, is fitted under the strip line, the cylinders being placed facing the blind holes and being able to enter them. The cylinders and their base are electrically conductive and connected to ground. |
