RF connectors are a type of connector used to transmit radio frequency signals by connecting transmission lines to various applications. In this blog, we will discuss five of the most common types of RF connectors: Bayonet Neill-Concelman (BNC), Subminiature A (SMA), Subminiature B (SMB), N-Type, and Threaded Neill Concelman (TNC). Before we look at RF connectors, it is important to understand how coaxial cables work. For a connector to transmit a radio frequency, there must be a transmission line. Coaxial cables are the most commonly used transmission line, as they have both inner and outer conductors, meaning coaxial cables experience less loss of signal and can be used in close proximity to metal objects without interference.
