A dielectric ceramic material essentially consists of a complex perovskite compound mainly composed of Ba(Mg1/3 Ta2/3)O3 phase and 0.005 to 1.0% by weight of phosphorus with reference to the complex perovskite compound. As one of the dielectric properties, the unloaded Q value reaches 37000 at a measuring frequency of 10 GHz and the temperature coefficient of the resonant frequency is about 4 ppm/ DEG C. |
