Transition: Understanding the Anatomy of a BNC Cable

Specifications and Characteristics

BNC cables are characterized by their distinctive locking bayonet connector, which securely mates two coaxial cables. The connector features a male pin on one end and a female receptacle on the other. When mated, the bayonet mechanism locks them together, ensuring a tight and reliable connection. BNC cables typically utilize coaxial cables with characteristic impedances of 50 ohms or 75 ohms.

The frequency range of BNC cables varies depending on the cable type and connector design. Standard BNC cables cover frequencies up to 4 GHz, while precision or high-frequency BNC cables can handle frequencies exceeding 10 GHz. The bandwidth of BNC cables can be further extended by using specialized connectors and dielectrics.
