26.5 GHz Stranded-Core High-Voltage Ultra-Flexible Low-Loss RF Cable F60

Engineering Note

The F60 is a high-voltage ultra-flexible low-loss RF coaxial cable for tight enclosure routing, RF test assemblies, phased array radar interconnects, and harsh outdoor microwave paths. Its stranded silver-plated copper inner conductor, LD PTFE dielectric, silver-plated copper strip inner shield, silver-plated copper wire braid outer shield, and 6.00 mm black PUR jacket support flexible microwave routing up to 26.5 GHz, with confirmed 1700 V.DC dielectric withstand voltage, 30 mm static bending radius, and >90 dB shielding effectiveness.
