Method for manufacturing high frequency electromagnetic wave transmission line that is coupled to e.g. semiconductor, involves utilizing air-filled cavities for attenuation of air or vacuum, where cavities are produced by covering

摘要

The method involves utilizing air-filled cavities (4) for attenuation of air or vacuum for loss-free coupling of components using high frequency signals, where the cavities are produced by a covering (2) using an additive process. The covering is made of electrically conductive material, and walls of the cavities are metallized such that a wave guide for electromagnetic waves is produced. Lateral walls and a base of the cavities are metallized, and end faces of the cavities are non-metallized such that a metallic conductor is integrated into the wave guide.
