BNC to SMA Cable Assemblies

Amphenol RF BNC to SMA Cable Assemblies feature straight or right-angle BNC plugs to straight or right-angle SMA connectors on RG-58, RG-142, and RG-316 cables. The BNC connectors feature a bayonet coupling style that enables quick connections and disconnections while providing high reliability. These assemblies can be used for both 50Ω and 75Ω impedance applications. The 50Ω assemblies will function up to 4GHz, and the 75Ω assemblies will function up to 3GHz. Amphenol RF BNC to SMA Cable Assemblies are ideal for broadcast applications.
