A process for the adjustment of the coupling factor of a strip line and strip line coupler of the directional coupler.

摘要

Arranged on a printed circuit board because in the case of the conductor plates starch, the thickness and the distances of the strip conductors, is selected to achieve a outside the predetermined coupling factor. Starting from the finding that a casting compound (vm), the electrical properties of a strip (k) is changed, the striplines with a potting compound (vm) cast, in order specifically to adjust a predetermined coupling factor.
