Properties, Test Methods, And Mounting Of Dielectric Resonators By Trans-Tech Inc.
The most important material properties for a dielectric resonator (DR) are its dielectric constant (εr), unloaded quality factor (Qu), and temperature coefficient of the resonant frequency (τf). The usual reason for choosing a DR as a resonating element is the size reduction afforded by the high (εr) of modern ceramics. But "dielectric constant" is a misnomer; not only does (εr) vary slightly for different temperature coefficient blends within the same material family, but lot-to-lot ceramic process variations cause (εr) to swing typically ±1 unit between lots.
