摘要： 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. The dielectric constant of rutile has an opposite temperature dependence to that of sapphire, and the thicknesses of the temperature compensating layers are selected such that the frequency of resonance of the resonator is maintained within a predetermined range over a predetermined temperature range, for example 1 part in 1015 over a temperature range of 1 mK0.

摘要： 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.
