Abstract

Waveguide couplers are combined with λ/4 shifted distributed feedback resonators to produce Narrow Band channel dropping filters. With distributed feedback coupling parameters already realized today, one may construct banks of 40 channel-droppping filters with 10-GHz bandwidths each that do not mutually interfere. Each stage may also inject its own signal or reinject the tapped signal so that other stages can pick it up.
