  • Ultra-high frequency filter with a dielectric resonator tunable in a large band width
    Patent number: 4459570
    Abstract: A dielectric resonator ultra-high frequency filter tunable in a large band width in which each dielectric resonator is constituted by a dielectric component with a high dielectric constant, which is fixed relative to an enclosure and a component made from the same dielectric material which is movable relative to the first component, in such a way that the distance d between facing surfaces of these two dielectric components varies, leading to a variation in the tuning frequency of the filter by modifying the coupling conditions.
