RF cable is a cable that transmits electromagnetic energy in the radio frequency range, and is an indispensable component of various radio communication systems and electronic equipment, which is widely used in wireless communication and broadcasting, television, radar, navigation, computers and instrumentation. RF cables are usually divided into semi-flexible coaxial cables, low-loss cables, stable phase microwave cables, test cables, rolled cables and fine coaxial cables according to the use. RF cables and RF connectors can constitute RF components, RF connectors are mainly transmission line electrical connection or separation of components, and RF components is a complete transmission can complete the RF signal and energy transmission cable. Cable assembly in the transmission system is a very critical part of its performance will seriously affect the transmission system quality of work. 2021 China RF cable market size reached more than 80 billion yuan, is expected to 2025 market size will be further expanded to 120 billion yuan. China's radio frequency coaxial cable market size is getting bigger and bigger, the reason why its development trend is very good, because its characteristics just to meet the social development of information transmission needs, is the development of the times can not be ignored.
