26.5 GHz Stranded-Core High-Voltage Ultra-Flexible Low-Loss RF Cable F50

Engineering Note

The F36 is an ultra-flexible low-loss RF coaxial cable for tight chassis interconnects, frequent-bending RF test assemblies, phased array radar routing, and harsh outdoor cable 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 3.60 mm blue PUR jacket support flexible microwave routing up to 40 GHz, with confirmed 18 mm static bending radius, 500 V.DC dielectric withstand voltage, and >90 dB shielding effectiveness.
