What are BNC Connectors?

The BNC connector was developed by Paul Neill from Bell Labs, and Carl Concelman from Amphenol, hence getting the name - "Bayonet Neill-Concelman" or BNC. This is a two-stud bayonet-style connector that has a twist and snap design with interlocking studs and slots. It is designed for quick mating, with the tactile 'snap' providing positive confirmation. BNC connectors can operate at frequencies up to 11 GHz.
