The 5th Generation Mobile Communication Technology (5G) is a new generation of broadband mobile communication technology with the characteristics of high speed, low delay and large connection. 5G communication facilities are the network infrastructure to realize the interconnection of man-machine and things. The performance improvement of the communication power supply comes from the improvement of the performance of the corresponding power components. Goford's multi-layer epitaxy process high pressure Cool MOS delivers excellent performance in terms of reliability, efficiency, radiation and more. At the same time, synchronous rectification combined with Goford SGT low voltage MOS further improves system performance.
