The radio frequency coaxial connector (RF connector) is generally considered to be a component installed on a cable or mounted on an instrument, as a component of a transmission line electrical connection or separation. It belongs to mechatronics products. Briefly, it mainly serves as a bridge.
RF connectors have a shorter history than other electronic components. The UHF connector that appeared in 1930 was the first RF connector. To the second world war, because of the war, with the development of radar, radio and microwave communication, the N, C, BNC, TNC series, such as medium, appeared after 1958 the miniaturization of products such as SMA, SMB, SMC, in 1964 established the United States military standard MIL - C - 39012 "standard of RF coaxial connector total", from then on, the RF connector began to develop in the direction of standardization, seriation, generalization.
In more than 60 years, through the joint efforts of national experts, the RF connector has formed an independent and complete professional system, becoming an important part of the connector family. It is the key component of coaxial transmission system. America, Britain, France and other countries of RF connector development technology in a leading position, its design, production, testing, use of technology have been fitting together of parts, perfect, not only formed a complete system of standards, and raw materials, auxiliary materials, test systems, assembly tools have been standardized, and specializes in mass production.
