Microwave dielectric ceramics are used in microwave band circuit as dielectric materials with one or multiple functions. They are the key materials of microwave components such as resonators, filters, capacitors, dielectric guided wave circuits etc, which are widely used in modern communication.
Application of microwave dielectric ceramics: mobile communication, satellite communication, military radar, satellite positioning and navigation system, automobile navigation, etc.
Application of ceramic dielectric filter: filter is an important part of base station RF devices, which is widely used in communication base station and terminal RF signal processing module. The advantages of ceramic dielectric filter are small size, light weight and low cost under the same frequency requirements.
Below products of Zehui Group are applicable for microwave dielectric ceramics.
