Temperature-independent dielectric resonator

摘要

A (TM01) dielectric resonator (200) has a metal housing, a dielectric insert (210), and a resilient element (218) 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.
