18 GHz 2000 V.DC Ruggedized Low-PIM High-Power RF Cable B63

Engineering Note

The B63 is a high-power flexible RF coaxial cable positioned as the ruggedized 2000 V.DC 18 GHz option. It keeps the confirmed B-series construction with LD PTFE dielectric, aluminum foil interlayer, silver-plated copper shielding, and blue FEP jacket, while emphasizing 2000 V.DC dielectric withstand voltage with a 6.35 mm blue FEP jacket. Use it for RF routes where the confirmed electrical class and cable size fit the system envelope.
