An Introduction to RF Coaxial Connectors
Abstract This article provides a comprehensive overview of Radio Frequency (RF) coaxial connectors, detailing their definition, types, key characteristics, selection criteria, and common applications, with a specific focus on popular series like SMA, TNC, and MMCX. 1. What is an RF Coaxial Connector? An RF Coaxial Connector is a component specifically designed for connecting coaxial cables within RF transmission systems. These connectors facilitate the interface between coaxial cables and other RF components, such as between coaxial cables and microstrip lines or between coaxial cables and waveguides. Typically, the plug component is attached to the cable end, while the jack (or socket) is mounted onto fixed equipment units. They are also commonly used for connecting two RF cables together. • Plug: The active part of the connection, usually featuring a coupling mechanism like a thread (nut) or bayonet lock. It is generally the free (non-fixed) connector. • Jack/Socket: The passive part...
