  • Method for making an ultra-high frequency transition between two orthogal guided structures and ultra-high frequency device with a transition of this type
    Patent number: 4887346
    Abstract: A method is disclosed for making an ultra-high frequency transition between two orthogonal guided structures and an ultra-high frequency circuit comprising a transition of this type wherein, in a first milling stage, a face is cut out of the mass in the angle formed by a guiding wall of the structure which is orthogonal to the first structure, without any tilting of either of the structures. The invention can be applied to ultra-high frequenices for millimeter waves.
