Specifications for BNC Connectors
BNC style connectors are miniature, light-weight, weatherproof interconnecting devices characterized by their two-stud, quick disconnect bayonet lock
coupling arrangement. Their design functions satisfactorily from DC to 11 GHz in static applications, or from DC to 4GHz in applications involving
vibration. The connectors typically yield a low VSWR (reflected signal) to 4GHz. Primary applications include radio telecommunications, broadcast
equipment, medical equipment, computer, Precision Video, High definition studio broadcast, video switching and test instrumentation where frequent
coupling and de-coupling are necessary. Bomar’s BNCs are available in an extensive variety of configurations and cable sizes and are impedance
matched to either 50 ohm or 75 ohm.
