1results about How to "Improve Microwave Performance" patented technology

This invention provides a microwave dielectric ceramic material and its preparation method for low ESR capacitors, belonging to the field of ceramic materials technology. By optimizing the composition and ratio of the main material, sintering aid, and modifying additives, this invention achieves both low dielectric constant and low ESR (high Q value) while maintaining an extremely stable temperature coefficient, effectively solving the problem of simultaneously achieving dielectric performance and temperature stability in existing technologies. The microwave dielectric ceramic material provided by this invention can be sintered in a reducing atmosphere and can be used to prepare low ESR, high Q value, and narrow temperature coefficient copper electrode multilayer ceramic capacitors, avoiding silver migration phenomenon in silver-internal electrode MLCCs, effectively improving device reliability and lifespan. It has broad application prospects in high-end fields such as communication base stations, radar, medical equipment, military industry, and AI servers, and the microwave capacitors prepared from it have significant practical value and market application prospects.
