Development of RF coaxial connectors

Radio frequency coaxial connector (hereinafter referred to as RF connector) is usually considered as an element attached to a cable or installed on an instrument as an element for electrically connecting or separating transmission lines. Belonging to electromechanical integration products. Simply put, it is mainly used as a bridge.

Compared with other electronic components, the development history of RF connectors is shorter. 1930 UHF connector is the earliest RF connector. During World War II, due to the urgent need of war, with the development of radar, radio and microwave communication, medium-sized series such as N, C, BNC and TNC appeared. After 1958, miniaturization products such as SMA, SMB and SMC appeared. 1964 formulated the American military standard MIL-C-390 12.

Over the past 60 years, through the joint efforts of experts from all over the world, RF connectors have formed an independent and complete professional system and become an important part of the connector family. It is an indispensable key component in coaxial transmission system. The development technology of RF connectors in the United States, Britain, France and other countries is in a leading position, and its design, production, testing and use technology has been complete and perfect. It not only formed a complete standard system, but also realized the standardization and specialized large-scale production of raw materials, auxiliary materials, testing systems and assembly tools.
