ABSTRACT:
A dielectric ceramic filter of the type which can be applied on high frequency application is provided. The filter includes a ceramic resonator and at least a ceramic capacitor. The ceramic capacitor is disposed between two adjacent resonators. The ceramic filtering capacitor includes a non-metal plate which has been coated with conductive coatings at the upper and lower surfaces respectively. A non-conducting material (or a strong dielectric membrane) having a dielectric coefficient is coated and disposed between said conductive coatings and it can be used in high frequency applications. Wherein the pass band of the filter can be readily defined or modified according to the system such that the signal pass band can be increased or decreased and the impedance rating of the signal can be optimally set to fifty (50) ohms.
