  • Miniature microwave filter comprising resonators constituted by capacitor-coupled rejector circuits having tunable windows
    Patent number: 4622528
    Abstract: The microwave filter comprises resonators constituted by capacitor-coupled rejector circuits. The tuning and coupling capacitors are composed of parallel metal plates supported and separated by the dielectric of a substrate. The surface of at least one plate of each tuning and/or coupling capacitor is provided with windows which can be sealed-off by a metal deposit in order to permit adjustment of each capacitor to its optimum value.
