16 × 16 Fast Switching Matrix, in the 3.7 - 4.2 GHz Band for Satellite Communications

The fast switching matrix studied and realized as a prototype by THOMSON-CSF DMH for INTELSAT and the CNET allows all possible interconnections between the 16 input ports and the 16 output ports. - It can be one of the essential elements of the future telecommunications satellites in the 4/6 and/or 11/14 GHz bands. - In its design, it is a complex sub-assembly which uses the most advanced technologies of the microwave integrated circuits. - It represents a record in the density of microwave components : 512 microwave PIN diodes grouped with their drivers in a 2 litre space. - This paper will show the various studies undertaken. In the first part, there will be a short description of the prototype that has been realized and the way in which it works. In the second part we present a more complete model from the technological point of view and which is now being realized.
