Dielectric ceramic composition for use in high frequency |
摘要 |
The present invention is a dielectric ceramic composition capable forming a dielectric resonator device provided with a high Q value at a high frequency band and keep a stable crystal phase when operated at a high power applied field. The dielectric ceramic composition which comprises a base composition expressed by the following chemical formula; BaO-x{(1-y)TiO2.yZrO2}; wherein 4.300</=x</=4.450 0<y</=0.10 and and additives of MnO2 and Ta2O5 in the following weight ratio against the base composition; 0<MnO2</=0.5 wt. % 0<Ta2O5</=1.2 wt. %
