-19- ABSTRACT OF THE DISCLOSURE In order to interconnect an unprotected bare chip of MMIC (microwave monolithic integrated circuit), a ceramic substrate carries a double-face circuit. A network of microstrip lines which radiate from the center to the periphery is disposed on the first face of said double-face circuit. The bare MMIC chip and its microwave environment is fixed on the second face which is metallized as a ground plane. The microwave circuit is interconnected with the network of microstrips by means of plugged metallized holes. A sole-piece provided with a housing for the MMIC is fixed on the ground plane. The first face can carry self-protected components.
