Abstract Translated from French Un tel mélangeur est réalisé sur deux sandwichs comportant chacun un plan de masse (24, 34), une couche dielectrique (21-31), et une couche gravée. L'une des couches gravées porte l'aneau mélangeur (AM) et les guides (G1, G2) d'entrée. L'autre couche gravée porte le guide de sortie (G3), et des organes d'adaptation. Les sandwichs sont accolés par leurs plans de masse et les diodes mélangeuses sont placées dans des trous qui relient les deux faces gravées. Réalisation de radars Doppler cohérents.
