RF Cables

Semi-Rigid and Flexible RF Cable Assemblies

St. Cross Electronics manufacture and supply a wide range of RF cable assemblies here in the UK. RF Cable assemblies are used to connect different equipment and systems surveillance, communications, and test equipment. They are divided into semi-rigid and flexible RF cable assemblies. Many elements need to be considered when choosing a great high-frequency cable: types of connectors, characteristic impedance, standing wave ratio (or reflection coefficient and return loss), attenuation, speed of dissemination, capacitance and inductance, normal rated voltage and power, frequency range, isolation, noise level, flexibility, environmental adaptability.

Rigorous Production Process With Nothing Left to Chance

As a manufacturer our partner naturally places a lot of emphasis on the supply and delivery of its connectors. The production process leaves nothing to chance and is the result of extensive research involving the critical factors: Operating Frequency, Characteristic Impedance, Skin Effect, Cutoff Frequency, Intermodulation, Voltage and Power Rating, Leakage.

From Specification to Finished Assembly, In One Place

RF performance is decided by what happens after the specification is agreed. Every assembly we build is made, inspected and tested at our Southampton facility, on machinery set up for the job: four automatic RF cable preparation machines, and a test regime covering return loss, VSWR, conductor impedance, insulation impedance and withstanding voltage. Our ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications are UKAS accredited and run as a single integrated management system. One site, one standard, no second facility interpreting it differently.

Electrical, Mechanical and Environmental Testing

A wide range of test are carried out to ensure what is delivered is correct and able to be used first time.

ELECTRICAL TESTING: Specialised test equipment is used to examine all types of products' return loss, VSWR, conductor impedance, insulation impedance, and withstanding voltage in order to meet international regulations.
MECHANICAL TESTING: Retention testers examine all products stress, pressure and damage tolerance.
ENVIRONMENT TESTING: We regularly conduct salt spray testing with our partner in order to ensure that the electroplating of each component meets the MIL standard.
