What is a ceramic dielectric filter?
2022.11.24
The ceramic dielectric filter is made of lead zirconate titanate ceramic material. The ceramic material is made into a sheet, and both sides are coated with silver as electrodes. After DC high voltage polarization, it has piezoelectric effect.
Ceramic dielectric filter using dielectric ceramic materials of low loss, high dielectric constant, low frequency temperature coefficient and thermal expansion coefficient, the role of the communication system is to select and control the signal frequency, select a specific frequency signal through, inhibit the unnecessary frequency signal.
Ceramic dielectric filter is mainly used in aerospace, microwave, mobile communication and other fields. In the rapidly developing field of 5G communication, ceramic dielectric filter may become the mainstream choice.
