18 GHz Ruggedized High-Voltage Ultra-Flexible Low-Loss RF Cable F80

Engineering Note

The F80 is a ruggedized high-voltage ultra-flexible low-loss RF coaxial cable for RF testing, phased array radar interconnects, outdoor microwave routing, and dynamic RF signal 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 8.00 mm blue PUR jacket support shielded microwave routing up to 18 GHz, with confirmed 1700 V.DC dielectric withstand voltage, 40 mm static bending radius, and >90 dB shielding effectiveness.
