The radio frequency coaxial connector is a general term for connectors used in the radio frequency coaxial feeder system. The connector is used for connecting radio frequency coaxial cables in radio frequency transmission lines used by communication and electronic equipment and similar electronic equipment. Or coaxial and microstrip connection between coaxial and waveguide. The plug part is usually installed at the end of the cable, and the socket part is usually installed on the equipment fixing unit, and is also used for the connection between the two radio frequency cables. Radio frequency coaxial connector, also called RF connector. "R" is the first letter of RADOI (radio frequency), and "F" is the first letter of FREQUENCY (frequency).
A radio frequency coaxial connector (hereinafter referred to as an RF connector) is generally considered to be a component mounted on a cable or mounted on an instrument that is electrically connected or separated as a transmission line. It belongs to mechanical and electrical integration products. To put it simply, it serves as a bridge.
Compared with other electronic components, RF connector has a short history of development. The UHF connector, which appeared in 1930, was the earliest RF connector. The two World War, because of the war needs, with the development of radar, radio and microwave communication, N, C, produced BNC, TNC, and other medium-sized series, 1958 after the miniaturization of products SMA, SMB, SMC, 1964 formulated the American military standard MIL-C-39012 "general specification for radio frequency coaxial connectors" since then, the RF connector, began to standardization and universalization of the direction of development.
In the past more than 60 years, through the joint efforts of experts from various countries, RF connectors have become an independent and complete professional system and become an important part of connector family. It is an essential component of coaxial transmission system. The RF connector the United States, Britain and France and other countries to develop technology in a leading position, its design, production, testing, use of technology has complete set, perfect, not only the formation of a complete standard system, and raw materials, auxiliary materials, transmission test system, assembly tools have also been standardized, and specialized production scale.
