The BNC series RF coaxial connector is a bayonet-type RF coaxial connector developed in accordance with the US military standard MIL-C-39012. It has the characteristics of rapid connection and reliable contact, and is one of the most widely used and used connectors in the world. The characteristic impedance of the BNC series RF coaxial connector is divided into 50Ω and 75Ω, and the sizes of the two different impedance connectors are matched.
Main Technical Specifications:
◆ Characteristic Impedance: 50Ω/75Ω
◆ Frequency Range: DC-4GHz(50Ω)/DC-1GHz(75Ω)
◆ Insulation Resistance: ≥5000MΩ
◆ Dielectric Withstand Voltage: 1500V(rms)
◆ Voltage Standing Wave Ratio (VSWR): ≤1.25
◆ Mating Cycles: 500 times
