Engineering Note
The C22G is a 40 GHz phase-stable semi-rigid coaxial cable designed for precision internal RF routing where phase stability, low loss, shielding, and elevated temperature capability are key selection factors. Its construction uses a silver-plated copper inner conductor, ultra-low-density PTFE dielectric, and seamless copper tube outer shield, supporting phased array radar signal paths, avionics and aerospace RF systems, precision instruments, and high-end microwave module interconnects. The cable provides 81% velocity of propagation, <750 PPM phase stability from -45°C to 85°C, and operation up to 40 GHz.
