Abstract: A method is provided for the sealed assembly of an electronic housing containing one or more electronic components. The method includes: assembling the housing by bringing a support, to which the electronic components are fixed, in contact with a cover by means of a mixture-including a paste and nanoparticles in suspension in the paste. The size of the nanoparticles range from 10 to 30 nm. The housing is closed in a sealed manner by heating the housing to a temperature T of between 150° C. and 180° C. making it possible to sinter the metal nanoparticles, while subjecting the housing to a pressure greater than 2.5×105 Pa.

Abstract: A signal transfer device which can be used to transfer a signal through a wall of a power package including a base, the wall bounding an internal part and an external part, said device including a first signal line portion outside the package; a second signal line portion inside the package; and a third signal line portion connecting the other two portions, wherein the first portion is shifted from the wall so as to respect a predefined safety distance; and the third portion is buried over its entire length.

Abstract: A Wilkinson coupler mounted on a printed circuit comprises a first access port connected to a second access port and to a third access port by way of two metallic transmission lines of the same length and a load resistor mounted in short-circuit arrangement between the second and third access ports, characterized in that the load resistor is constituted of three adjacent independent resistors linked together. The coupler applies notably to the field of satellite antennas and more particularly to antenna beamforming arrays.

Abstract: A hybrid microwave circuit device comprises a base provided with an external peripheral wall and at least one internal wall together delimiting at least two cavities to accommodate hybrid microwave circuits and a cover which is made of the same material as the base.
