摘要： A (TM01) dielectric resonator has a metal housing, a dielectric insert, and a resilient element located between one end of the dielectric insert and the housing. The resilient element ensures physical contact between the housing and both ends of the dielectric insert over the entire operating temperature range of the resonator, thereby compensating for differences in the coefficients of thermal expansion of the materials used for the metal housing and the dielectric insert. In one embodiment, the dielectric insert is housed within a cylindrical tube between a top cover and a bottom end cap, the resilient element is an electrically non-conductive (silicone rubber) gasket, and the resonator has a thin, electrically conductive (aluminum) plate located (i) between the dielectric insert and the gasket and (ii) between the end cap and the tube to ensure a contiguous electrically conductive path from one end of the dielectric insert to the other.
