Abstract

A circulator with at least three ports (p1, p2, p3) comprises two identical electromechanical micro-switches of the series type (MEMS1, MEMS2) 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 (p1) to a port (p2) designed to be connected to an antenna, a second micro-switch being disposed in order to allow the signal transmission between the port (p2) designed to be connected to an antenna and said output port. Application to a radiofrequency or microwave telecommunications system.
