Description

This paper deals with a novel additive micro-fabrication process for millimeter-wave components. This fabrication process is based on successive lithography, metal electroplating with micron scale accuracy, well suited for millimeter-wave filter fabrication. As an additive fabrication process, the millimeter-wave components can be fabrication on many types of substrates, like PCB or ceramics. First prototypes of air-filled copper cavities and filters have been realized with this process and the prototypes can reach an unloaded quality factor between 450 and 1000 for frequencies between 35 GHz and 140 GHz.

JUSTIFICATION FOR THE CONSIDERATION

Please find attached the abstract entitled “Additive Micro-Fabrication of High Q Millimeter-Wave Cavities and Filters”. This work, realized in partnership with the CNES, shows an interesting way to fabricate high performance millimeter-wave components with standard lithography and electroplating processing.
