Engineering Note
The W22 is a 40 GHz compact phase-stable low-loss flexible RF coaxial cable designed for precision microwave interconnects, avionics routing, phased array radar, ECM systems, and high-frequency RF assemblies where phase consistency, low loss, and compact cable routing are required. Its 2.20 mm gray PFA jacket, LD PTFE dielectric, silver-plated copper inner conductor, silver-plated copper strip inner shield, and silver-plated copper braid outer shield support stable signal transmission in demanding microwave environments. The cable combines DC–40 GHz operating capability, <750 PPM phase stability, -155 dBc low PIM performance, and >90 dB shielding effectiveness for compact phase-critical RF interconnect applications.
