Abstract
A poly-band filter includes a folded metal housing which defines an interior region partitioned by a divider. First and second pluralities of resonators are provided in the housing. Alternately increasing and decreasing degrees of coupling are provided between adjacent resonators in the housing. Slot coupling is provided between first and second non-adjacent resonators displaced from input/output connectors for the filter.
