Catalogue values support selection. Final tolerances, assembly performance and acceptance tests are defined in the approved drawing and specification. No certification is implied.
Microwave coaxial cables using silver-plated bimetallic alloy in the centre conductor and mechanical protection layer, for weight-sensitive airborne and space equipment routing.

Typical attenuation at +25 °C and sea level. Source test lengths: 10 m for CM-COAX-PS-LW-OD2P20; 20 m for the other four models. Compare mass for the same diameter and installation requirement; weight saving is not a fixed percentage for every model.
Impedance: 50 Ω | All listed models
Cutoff frequency: 18 GHz | Listed cable models
Operating temperature: −55 to +125 °C | Finished cable
