One of the most popular of the coaxial connectors, the BNC was developed in the late 1940's. The name BNC stands for Bayonet-Neill-Concelman. Bayonet describes the coupling mechanism, while Neill and Concelman were the inventors of the N and C connectors.
BNC connectors are available in 50 and 75 ohm impedances, and are intermateable with each other. The 50 ohm designs operate up to a frequency of 4 GHz. BNC connectors are used in many applications, some of which are flexible networks, instrumentation and computer peripheral interconnections.
