26.5 GHz 6-Layer Heavy-Duty High-Voltage Phase-Stable Low-Loss RF Cable W54

P/N: W54

  • 6-layer build for heavy-duty RF protection
  • Phase-stable path for precision microwave systems
  • High-voltage structure for demanding routing
  • LD PTFE interlayer for added durability
  • Built for avionics and ECM environments
Engineering Note
The W54 is a 26.5 GHz 6-layer heavy-duty high-voltage phase-stable low-loss flexible RF coaxial cable designed for precision microwave interconnects, avionics routing, phased array radar, ECM systems, and rugged high-frequency RF assemblies where phase consistency, voltage withstand, low PIM behavior, and heavy-duty cable protection are required. Its advanced 6-layer construction adds an LD PTFE interlayer between the inner shield and outer shield, improving structural durability while maintaining stable microwave transmission. The cable combines a 5.40 mm gray FEP heavy-duty jacket, LD PTFE dielectric, silver-plated copper conductor, dual silver-plated shielding, DC–26.5 GHz operating capability, <750 PPM phase stability, 1500 V.DC dielectric withstand voltage, -155 dBc low PIM performance, >90 dB shielding effectiveness, and an extended -55 °C to +165 °C temperature range for rugged phase-critical RF interconnect applications.
