3D microwave modules for space applications

Abstract
This paper describes the design, manufacturing and measurement of 3D microwave modules. The vertical interconnection between stacked circuits is based on an shielded homogeneous coplanar line with a 90/spl deg/ vertical structure. The fabrication of these modules is in relation with the "MultiChip Module Vertical" technology, originally developed for digital applications. The electrical measurement in the Ku-band demonstrates very good results. Author(s) Monfraix, P.
