  • Patent number: 6580933
    Abstract: A resonator for rf frequencies, especially microwave, in telecommunications systems, with an extremely stable resonant frequency over a desired operating temperature range, of predetermined width (Y) and thickness (X) and having a predetermined length (Z) in the direction of propagation for achieving a desired resonance, comprises a dielectric substrate of rutile, and first and second temperature compensating layers of sapphire on two opposite faces of the substrate and extending along the length of the substrate, these sapphire layers having a predetermined thickness, and first and second superconducting layers formed on the outer surfaces of the temperature compensating layers.

  • Patent number: 6563401
    Abstract: The dimensions of a resonator filter comprising at least one puck (12, 14) in a metal cavity (16) are calculated by deriving the diameter c and thickness j of the puck, the spacing of the puck from the cavity walls by a mode-matching technique, then optimized by applying electromagnetic simulation of a full filter response. Other dimensions of the puck may also be optimized. If two or more pucks are present in the cavity, the inter-puck spacing is also optimized.

  • Publication number: 20020005766
    Abstract: In order to provide a resonator for rf, especially microwave frequencies, for use in mobile telecommunications systems and satellite communications systems, with a particularly high Q value, the resonator, of predetermined width (Y) and thickness (X), and having a predetermined length (Z) in the direction of propagation for achieving a desired resonance, comprises a dielectric substrate, and first and second dielectric layers on two opposite faces of the substrate forming mirrors at which electromagnetic waves propagating along the length of the substrate will experience internal reflection, the dielectric layers having a predetermined thickness and having a dielectric constant less than that of the substrate. First and second conductive layers are formed on the outer surfaces of the dielectric mirrors. The substrate may be formed of sapphire and the dielectric mirrors of MgO. The conductive layers may be normal conductors or superconducting HTS layers.
