University of Science and Technology of China has made major achievements in the field of 6G filtering

The 5G era has not yet begun, and the 6G era has begun to be deployed. Internationally, there has been controversy over the electromagnetic spectrum above 6GHz. However, with the development of 5G to Beyond 5G) and 6G, most countries have begun to consider using this frequency for cellular use. Wireless communication, however, has not achieved significant results.

On May 21, 2022, the University of Science and Technology of China announced that it has made important progress in the field of 6G filters, realizing a high-frequency MEMS resonator with a high quality factor of over 100,000, breaking through the product of resonator and Q value for the first time. The Q value has been increased by 2 orders of magnitude, and the limit of merit of the resonator has been improved. In the work, a new mechanism for regulating the dielectric loss and acoustic loss of lithium niobate thin films has been discovered by using three-dimensional Euler angles, which will provide a basis for future micro-nano The device opens up more possibilities in application fields such as high-frequency wireless communication, medical ultrasound imaging, intelligent information processing, and IoT sensors, and plays an important and positive role in the development and implementation of 6G technology.

The 6G filter has long been the core of the 6G development technology, because the 6G filter can filter out the interference noise after receiving the signal, leaving only the specially designated frequency to pass through for spectrum analysis, which acts as a filter . Filters are the key technology for the development of wireless communication in the next stage. They are also the basic radio frequency components and chips that must be independently controllable in the development of 6G technology in China. The research breakthrough has successfully accelerated the technological development of my country’s radio frequency spectrum and promoted the layout of my country’s satellite-to-earth network.

The successful breakthrough of 6G filtering technology not only brought 6G processors to the public, but also indirectly promoted the integration between 6G private networks and low-orbit satellites, breaking the technical barriers of Western countries’ monopoly on 6G. Although 6G technology is still in the development stage, it is believed that with the continuous research and development of Chinese researchers, 6G technology will completely enter our lives in the near future and join hands with us in the future.
