Abstract: A dielectric resonator having a high effective dielectric constant, a high effective Q and a low effective temperature coefficient of dielectric constant is realized by a composite resonator comprising a first member including a paraelectric material such as, for example, TiO2 and a second member comprising either the ferroelectric material LiTaO3 or the ferroelectric material LiNbO3. Additionally resistive means applied to the ferroelectric material reduces the increased variations of the effective temperature coefficient of the resonator during rapid temperature changes. This feature is applicable to any microwave device incorporating a pyroelectric ferroelectric.
