Developed as a miniature version of the Type C connector, the BNC connector is a miniature quick mating and de-mating RF connector. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. SV Microwave's 50 Ohms BNC series connectors are miniature and lightweight. They are designed to operate at a frequency of DC to 11 GHz and typically yield low reflection through 4 GHz.
