BS EN 16602-70-18 defines the technical requirements and quality assurance provisions for the assembly and mounting of high-reliability, radiofrequency (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 under BS EN 16602-70-18 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, not covered by the BS EN 16602-70-18, is covered in ECSS-Q-ST-70-08.
BS EN 16602-70-18 on the preparation, assembly and mounting of RF coaxial cables is relevant to:
RF coax is defined by three elements consisting of a centre conductor, an outer conductor, and an insulating spacer between the two conductors. Coaxial cables use a centre conductor to transmit electrical signals, generally comprised of a single solid copper wire. Coaxial cables are used for the transmission of Radio Frequency energy where tight impedance and RFI/EMI control are required.
BS EN 16602-70-18 assists you with the principles of reliable soldered or crimped semi-rigid cable connections and prerequisites for assembly and mounting of semirigid coaxial cables to manufacture coaxial cables of high quality and durability.
BS EN 16602-70-18 also guides you regarding the preparatory conditions and material selection of coaxial cables, preparation of semirigid cables, preparation for soldering assembly of semirigid cables and assembly of connectors to RF coaxial cables, mounting of cables, and process verification of coaxial cables. This assists in improving and enhancing the efficiency and durability of RF coaxial cables.
