1 Scope
This document specifies the required characteristics of coaxial cables, 50 Ω, type WD, for use in aircraft
electrical systems at operating temperatures between –55 °C and 200 °C and specially for high
frequency up to 6 GHz. The thermal stability test has demonstrated acceptable performance at -65 °C.
