67 GHz Compact RF Precision Test Cable T24

Engineering Note

The T24 is a 67 GHz compact RF precision test cable designed for high-frequency microwave testing, avionics equipment, ECM systems, and precision laboratory setups where routing space, bend resistance, and signal integrity are key selection factors. Its construction uses a silver-plated copper inner conductor, low density PTFE dielectric, silver-plated copper strip inner shield, low density PTFE interlayer, silver-plated copper wire braiding, and a blue FEP jacket. The cable supports compact test routing while providing 81% velocity of propagation, >90 dB shielding effectiveness, 500 V.DC dielectric withstand voltage, and operation up to 67 GHz.
