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&#xb0; 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&#xb0; to within 20&#xb0;.

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 (), each filter comprising at least two coupled resonators, at least one resonator (Rs, Rs) being common to two different filters, and each input port and each output port being connected directly to at least one resonator. The router device is capable of appropriately performing routing in which it is possible to supply on at least one output port an output multiplex having at least a first and a second frequency channel, among which: the first frequency channel has originated from a first input multiplex, supplied on a first input port and comprising said first frequency channel, and at least one further frequency channel forwarded to a second output port of the device; and the second frequency channel is either forwarded from a second input port, or, when the first input multiplex comprises at least three different multiplexed frequency channels, the second frequency channel originates from the first input multiplex, the first second frequency channels, being frequentially disposed on both sides of a third frequency channel, with the said third frequency channel being routed to a different output port.
