In recent years, a time-division switching method (SS/TDMA) in which a microwave switch matrix (hereinafter referred to as MSM) is mounted on a communication satellite has been put into practical use. As satellite communication capacity increases, the size of MSM increases.
That is, the number of microwave input/output ports tends to increase, and on the other hand, there is a strict requirement for miniaturization of the shape.

In contrast, a large-scale MSM is configured by connecting multiple microwave signal distributors and microwave signal combiners with multiple two-dimensional MSM units with a small number of microwave input/output ports using microwave signal transmission cables. A method is also being considered (Patent Application No. 55-4364). However, with this method, the number of microwave signal transmission cables used increases in proportion to the number of microwave input/output ports, so the space for laying the cables increases, and the cables are crossed, resulting in increased rigidity. There are disadvantages such as the small cable's low vibration resistance.
