Description:

This project focuses on developing a high efficiency RF system and aims at the existing system (4G) as well as the future network (Beyond 4G). This project will focus on four major areas to increase the spectral and power efficiency of RF systems. The four major areas include (1) high efficiency power amplifier, (2) closed loop RF system, (3) panel antenna array and (4) maximum ratio combining (MRC). These technologies can provide higher spectral efficiency and reduce the power consumption of the wireless system. The project will utilize some technological achievements from the prior projects: “5G RF Front-end Systems” and “Active Antenna System Development Platform”. The technologies of this project will provide immediate applications in the infrastructure market of the communications industry. Many companies such as Sunnada, Rohde & Schwarz and TCL already expressed strong interest to support this project. The new technology will also enable collaborations or joint R&D with both the industry and other domains within ASTRI to upgrade the technical capability and competiveness of the communications industry in Hong Kong and the region.
