Abstract
An inter-resonator coupling scheme for a filter is disclosed. An inter-resonator coupling member is located between successive resonators in the filter. By adjusting the length and/or the proximity of the inter-resonator coupling member relative to the adjacent resonators, the ratio of energy transferred from resonator to resonator (via the inter-resonator coupling member) may be increased and/or decreased. By increasing the ratio of energy transferred from resonator to resonator, the bandwidth of the filter is increased and is made relatively insensitive to tuning which may occur via manipulation of field disturbances introduced by tuning tips. The inter-resonator coupling member is made of a conductive or superconductive material and contains at least three sections. The first section runs substantially parallel to an edge of the first resonator that is not profoundly influenced by the source of field disturbance. The third section runs substantially parallel to an edge of the second resonator that is not profoundly influenced by the source of field disturbance. A second section connects the first and third sections.
