According to foreign media reports, electrical engineers at the University of California, Irvine (UCI) have invented a new wireless transceiver that can increase the radio frequency to 100 gigahertz, which is four times the speed of the 5G wireless communication standard.

This 4.4mm square silicon chip is called "end-to-end transceiver" by its inventor. Due to the unique digital analog structure, the digital signal processing speed is faster and the energy efficiency is higher. The team's innovations were published in the recent IEEE Solid State Circuit Magazine.

Payam Heydari, director of the NCIC laboratory and professor of electronic engineering and computer science at UCI, said, "The chip speed and data rate are two orders of magnitude higher than the performance of the new wireless standard. In addition, its higher operating frequency means that everyone can use it Operators provide greater bandwidth. "

He also said that academic researchers and communication circuit engineers have been exploring whether wireless systems can achieve the high performance and speed of fiber optic networks. If it can be achieved, it will change the telecommunications industry because wireless infrastructure has more advantages than wired systems. The transceiver will surpass the 5G wireless standard, specify the operating frequency between 280 and 380 gigahertz, and move towards the 6G standard. The operating frequency of the 6G standard is expected to be above 1000 gigahertz. Transmitters and receivers capable of handling such high-frequency data communications are essential for creating a new wireless era dominated by the Internet of Things, autonomous vehicles, and the rapid development of high-definition video content streaming broadband.

Heydari said that changing the signal frequency of the transceiver through modulation and demodulation is traditionally done through digital processing. But integrated circuit engineers have seen the physical limitations of this method in recent years. He explained, "According to Moore's Law, we can reduce the size of the transistor to increase its speed. But now the situation is different, we can not divide the electron into two." To solve this problem, NCIC laboratory researchers use a chip The architecture greatly reduces the digital processing requirements by modulating the digital bits in the analog and RF domains.

Huan Wang, one of the authors of the paper, a PhD student in electrical engineering and computer science at the University of California, and a member of the NCIC laboratory, said that the technology combined with a phased array system, using multiple antennas to control the beam, can promote many disruptions in the field of wireless data transmission and communication. Sexual application. He also said, "Our innovation in the data center is no longer needed the miles of fiber optic cable, data field operators can be ultra-high-speed wireless transmission, and save a lot of money in hardware, cooling and electricity."
