Filter having electrical circuit arrangement with concentrated elements in multi-layer substrates |
摘要 |
An electrical circuit arrangement provides a substrate and at least two conductive surfaces. The substrate comprises at least one layer disposed between the conductive surfaces. The conductive surfaces form a capacitor and overlap in part and form an overlapping area. In the event of a displacement of the conductive surfaces relative to one another, the resulting overlapping area is largely constant up to a threshold value of the displacement. |

1. A filter with at least one electrical circuit arrangement comprising a substrate and at least two conductive surfaces, wherein
the substrate comprises at least one layer, the at least one layer of the substrate is disposed between the at least two conductive surfaces, the at least two conductive surfaces form a first capacitor, the at least two conductive surfaces at least partly overlap and form an overlapping area, and the overlapping area is largely constant at displacement of the at least two conductive surfaces relative to one another up to a threshold value, wherein the filter contains a first inductance, the first inductance is concentrated, the first inductance is realized as a conductive strip on the substrate, the conductive strip, which forms the first inductance, provides a curve and/or is arranged in the form of a loop and/or a spiral, and the filter is a differential two-port filter that provides an all-pass characteristic and generates a phase distortion. |
