Dielectric material for microwave of CaTIO3-La(Mg1/2Ti1/2) O3-LaAlO3 group |
摘要 |
The present invention relates to a dielectric material for a microwave of a CaTiO3-La(Mg+E,fra 1/2+EE Ti+E,fra 1/2+EE )O3-LaAlO3 group. The dielectric material for a microwave according to the present invention includes a composition condition of 0.3</=x</=0.6 and 0</=y</=1.0 wherein (1-x)CaTiO3-x[(1-y)La(Mg+E,fra 1/2+EE Ti+E,fra 1/2+EE )O3-yLaAlO3]. The high frequency dielectric material includes an dielectric constant of above 40, a low dielectric loss, and a temperature coefficient of a resonant frequency which is easily variable from a positive (+) value to a negative (-) value with respect to the value of 0 ppm/ DEG C.
