ECSS-Q-70-18A – Preparation, assembly and mounting of RF coaxial cables (31 August 2001)

This standard has been cancelled and replaced by ECSS-Q-ST-70-18C (15 November 2008).


This Standard defines the technical requirements and quality assurance provisions for the assembly and mounting of high-reliability, radio-frequency (RF) coaxial-cable interconnections for use as transmission lines in spacecraft and associated equipment.

In general, these assemblies are designed for low-loss, stable operation from the relatively low frequencies through the higher frequencies in the microwave regions.

These transmission-line cables should not be confused with low-frequency cables with conductive sheaths (usually copper braid), which are used in applications where shielding of the centre conductors from the surrounding electrical ambient is required. The interconnection of those shielded cables is covered in ECSS-Q-70-08.
