MULTISECTION WAVEGUIDE DIRECTIONAL FILTER.
Abstract
A five-section waveguide directional filter was fabricated and evaluated with regard to its practical use as a multiplexing filter. The use of multi-section filters is desirable in a practical multiplexing system due to the need for increased selectivity to isolate adjacent channels. In addition, a relatively broadband coupling technique has been investigated which permits the realization of bandwidths that are greater than a fraction of 1%, which up to now have been typical for these devices. A 1.3% bandwidth has been achieved using a two-slot iris geometry for the end couplings. The various problem areas associated with fabricating and testing the device are discussed and certain recommendations are made which should eliminate their causes and result in a further improved filter.
