  • Bandpass microwave filter tunable by relative rotation of an insert section and of a dielectric element
    Patent number: 9620837
    Abstract: A bandpass filter for microwave-frequency wave which is frequency tunable, comprises at least one resonator. Each resonator comprises a cavity having a conducting wall substantially cylindrical in relation to an axis Z, and at least one dielectric element disposed inside the cavity. The resonator resonates on two perpendicular polarizations having respectively distributions of the electromagnetic field in the cavity that are deduced from one another by a rotation of 90° and according to one and the same frequency. The wall of the cavity comprises an insert section facing the element having a different shape from a section not situated facing the element. The insert section and the element are able to perform a rotation with respect to one another in relation to the axis Z so as to define at least a first and a second relative position differing by an angle substantially equal to 45° to within 20°.

  • Compact multi-port router device
    Patent number: 9391585
    Abstract: The invention relates to a multi port router device capable of carrying a number P, which is greater than or equal to three, of frequency channels, from a number M of input ports to a number N of output ports, at least one of the two numbers M and N being greater than or equal to two, characterized in that it includes at least two filters (12, 14, 16, 18), each filter comprising at least two coupled resonators, at least one resonator (Rs1, Rs2) being common to two different filters, and each input port and each output port being connected directly to at least one resonator.
