As one of the most common used RF connectors, the BNC connectors is a gype of small bayonet connector that can achieve quick connection. Its full name is Bayonet Nut Connector. This series of connectors is available in 50Ω and 75Ω impedance specifications. The BNC series of RF coaxial connector is a bayonet connector based on US military standard MIL-C-39012.
The frequency of the BNC connector is generally 0~4GHz, and its special bayonet structure makes it have the advantages with quick connection and contact reliable and other advantages.
BNC series of RF coaxial connectors are mainly used in amateur radio antennas, avionics, test equipments, and other RF electronic equipments.
