Radiofrequency or hyperfrequency circulator

EMSEMSA circulator with at least three ports (p, p, p) comprises two identical electromechanical micro-switches of the series type (M, M) formed on the same substrate, a first micro-switch being disposed in order to allow the transmission of a radiofrequency or microwave signal from an input port (p) to a port (p) designed to be connected to an antenna, a second micro-switch being disposed in order to allow the signal transmission between the port (p) designed to be connected to an antenna and said output port. Application to a radiofrequency or microwave telecommunications system.
