<p>The present invention relates to superconducting multiplexing/demultiplexing arrangements (20) comprising a number of signal input means (21, 22) and a number of signal output means (25). A number of resonators (R20) provide(s) a number of filters wherein each filter represents a channel. The resonator(s) (R20) operate(s) at least in dual mode and tuning means are provided so that at least some of the resonators is/are tuneable. The invention also relates to a method of multiplexing signals incoming to a multiplexing arrangement with a number of resonators, each of the resonators having a number of input ports which are so arranged that a number of multipole filters are created. Input signals having different frequencies are supplied to the different input ports of the resonators each of which is operated in three modes. Coupling means are arranged which at least comprise the angle between the input ports and a symmetry plane wherein said angles are non-perpendicularly azimuth. Tuning means are further provided for tuning the resonant frequencies of the degenerate modes and the coupling angles and tuning means are controlled so that for a number of input signals, only one is transmitted to the output means.</p> |
