Abstract (en)
[origin: WO2007138101A1] The invention relates to a circulator having at least three ports (p1, p2, p3). Said circulator comprises two identical series-type electromechanical micro switches (MEMS1, MEMS2) formed on the same substrate, a first microswitch being arranged in such a way as to enable the transmission of a radiofrequency or hyperfrequency signal from an inlet port (p1) to a port (p2) to be connected to an antenna, and a second micro switch being arranged in such a way as to enable the transmission of a signal between the port (p2) to be connected to an antenna to the outlet port. The invention can be applied to a radiofrequency or hyperfrequency telecommunication system.
