Abstract

Microwave dielectric ceramics are a kind of functional electronic materials that have been rapidly developed in recent decades. They are widely used as dielectric materials in high frequency circuits operating in the microwave frequency range (300MHz–3000GHz), being capable of fulfilling one or more functions. These materials possess characteristics such as low loss, low temperature coefficient at resonant frequency, and high dielectric constant. They are used for many key microwave components such as dielectric resonators, dielectric filters, multiplexers, microwave dielectric antennas, and RF/microwave integrated modules for various applications, including mobile communications, satellite TV broadcasting, radar, and satellite-based navigation systems. Microwave dielectric ceramics have gained great attention in communications and defense industries, making them highly valuable materials.

Having had decades of persistent efforts, GOVA Technology has developed and achieved mass production of microwave dielectric ceramic materials with dielectric constants ranging from 4 to 90. Components such as dielectric resonators, dielectric waveguide filters, RF integrated modules, antennas, and related structural parts manufactured using these materials have already been applied, in large quantities, to 4G and 5G wireless communication systems, as well as U6G. In response to the market demands, materials and processes with specific properties, high levels of integration, and special structural requirements have also been developed, continuously meeting client needs for low cost, miniaturization, and high performance.

Speaker Biography

Mr. WU Yueguang received his Master degree from the Materials Engineering program at the Xiamen University in 1989. He is currently the Deputy General Manager of Guangdong Guohua New Materials Technology Co., Ltd. (广东国华新材料科技股份有限公司), primarily responsible for company's management in R&D and manufacturing processes.

With nearly ten years of experience in the development and manufacturing of microwave ceramics, he is highly experienced in areas including microwave dielectric ceramic powder development, ceramic process development and optimization, and large-scale production and efficiency improvement of dielectric filter projects. He has successfully developed the processes of laser automatic tuning, dual-layer dielectric filters, intermodulation improvement for dielectric filters, and mass production of large-size dielectric filters.

He will be continuously devoted to the preliminary R&D on higher-performing materials, lower-cost solutions, and structurally stable and reliable designs, thereby supporting customers with product upgrades and platform evolution.
