Japanese successfully developed chipset transceiver wireless data reach the highest speed in the world by CMOS technology rates of 640 Gbps.
Professor Kenichi Okada and his colleagues at The Tokyo Institute of technology has partnered with the Institute of information technologies and National Media to research and development of chip transceiver, wireless use band D new process 65 nm and CMOS technology (semiconductor complementary metal oxide silicon). The research results are presented at The seminar IEEE 2024, taking place October 16-20/6 in Honolulu, Usa.
According to Okada, remarkable points of the chipset is achieving high speed just by CMOS technology cheap, saves cost when mass produced.
Connectivity technology 5G is for the highest speed of 10 Gbps and operates in the frequency band 24-47 GHz, the longer the connection technology, the next generation are to research and development on the higher frequency. Meanwhile, the new chipset of Japan developed to operate on frequency bands from 114 to 170 GHz with a signal bandwidth of 56 GHz.
The researchers used circuit board integrated to create a receiver and a transmitter with IC for the development has the size to 1.87 x 3.3 mm and IC for the fall is 1,65 x 2.6 mm. In addition, the circuit can power amplifier to improve the signal to levels suitable, low noise amplifiers to boost the signal, an inverter to adjust the signal according to the frequency...
In the test configuration with multiple inputs and outputs (MIMO), the researchers used four modul generator and four modul receiver, in which each antenna can handle data streams separately. When using modulation 16QAM, speed per channel reaches 160 Gbps and total gain speed 640 Gbps, 100 times faster than with systems 5G available on the market.
This research is supported in part by the Ministry of Internal affairs and Communications Japan. Kenichi Okada said: “Chipset promises to be wireless systems, next-generation support auto, auto, medical, remote and virtual reality experience advanced”.
