BNC Coaxial Connectors
The Amphenol BNC connectors are made to high quality level. Medium size coaxial connectors with
bayonet lock. 50 ohm impedance for applications up to 4 GHz and 75 ohm impedance up to 2 GHz.
75 Ohm Series
Within the internationally standardized BNC mating face dimensions, a perfect 75 ohm characteristic
impedance cannot be realized. However, at frequencies up to 1000 MHz, the small impedance
deviation is negligible for practical applications. Amphenol true 75 ohm connectors with a typical
VSWR reading of 1.06:1 at 2000 MHz are identified by an asterisk following the part number.
All 75 ohm BNC connectors and 50 ohm BNC connectors are intermateable without restrictions.
