NOVEL MICROWAVE FILTER DESIGN TECHNIQUES.

Abstract

A trial bandstop filter in stripline form was designed with the aid of the elliptic-function bandstop filter design tables published in Quarterly Progress Report 2. The tests results were found to be in good agreement with the theory. A magnetically tunable UHF bandpass filter designed in strip transmission line and with two disk-shaped resonators of yttrium-iron-garnet (YIG) is described. Single crystals of both pure YIG and gallium-substituted YIG were used. Re-entrant directional couplers with direct-coupled center conductors are often easier to realize than similar re-entrant couplers that have no direct coupling between center conductors. New design equations for the former type are presented. (Author)
