An eight pole self-equalised quasi-elliptic superconductor planar filter for satellite applications

This paper discusses the design of an input multiplexer for satellite applications. The channel filters are self equalised eight pole high temperature superconductor (HTS) planar structures. Measured data shows the feasibility of this filter realisation with the cross loop resonators. A new configuration is proposed to annihilate the parasitic coupling and to obtain a compact structure. In this case, the responses are improved.
