DIELECTRIC MATERIAL FOR HIGH FREQUENCY AND RESONATOR MADE THEREOF, AND MANUFACTURE THEREOF.

摘要

A dielectric material for high frequencies, wherein a glass, an oxide aggregate having a dielectric constant whose temperature coefficient tau epsilon is positive, and an oxide aggregate having a dielectric constant whose temperature coefficient # tau# epsilon is negative are used, these are blended in a predetermined volumetric ratio, the temperature coefficient tau epsilon of high frequency dielectric material is about -12 ppm/ DEG C. Thereby the temperature coefficient tau f of the resonance frequency of the high-frequency resonator made of the dielectric material is about zero.
