Key Features

  • Materials: The 047 SERIES utilizes a silver-plated copper center conductor with a laminated PTFE dielectric, combined with silver-plated copper for both the foil and braid. The outer jacket is made of FEP, measuring 0.062 inches (1.63mm) in diameter, ensuring durability and environmental resistance.
  • Electrical Characteristics: Impedance of 50 ± 2Ω and provides a maximum cut-off frequency of 120 GHz (cable only). Capacitance is rated at 28.6 pF/ft, with a velocity of propagation of 71% and a time delay of 1.43 ns/ft. Shielding effectiveness remains above 90 dB up to 18 GHz, indicating exceptional performance in preventing signal interference.
  • Attenuation and Power Handling: The series features specific attenuation factors (K1 = 37.5, K2 = 0.935) and provides detailed attenuation values across a range of frequencies, from 0.5 GHz to 110 GHz, with corresponding power handling capabilities. This precise data enables users to select the optimal cable configuration for their specific application requirements.
  • Mechanical and Environmental Characteristics: The cable is lightweight at 0.08 oz/ft (7.4 g/m), with a static bend radius of 0.2 inches (5.1mm) and a dynamic bend radius of 0.375 inches (9.5mm). They are designed to operate within a temperature range of -65°C to +150°C and are RoHS 3 compliant, ensuring suitability for a wide range of environments and applications.
