This section describes the application scenarios of the RF coaxial cable.
RF coaxial cable components are divided according to physical characteristics, mainly semi-rigid cable, semi-flexible cable and flexible/ultra-flexible cable three, different applications should choose different types of cable. In general, semi-rigid and semi-flexible cables are generally used for interconnection within the equipment; In the field of testing and measurement, flexible cables are mostly used.
1. Semi-rigid cable
High hardness, not easy to be bent forming, bending requires a professional forming machine, the performance is relatively stable; Excellent shielding performance, the internal filling medium is solid polytetrafluoroethylene material, good phase stability, widely used in various RF and microwave systems.
2. Semi-flexible cable
The high density round wire braided tinned outer conductor makes the semi-flexible cable have the advantages of strong tensile strength and good bending formability, and can be formed by hand. It has the characteristics of high frequency, low voltage standing wave ratio and high shielding efficiency.
3. Flexible/ultra-flexible cable
"Test level" cable, suitable for scenarios with relative displacement (reciprocating, dragging). Test cables have high requirements for flexibility and performance indicators, flexible cables are easy to bend multiple times and can maintain performance, and the process is complex, so the price is high.
RF coaxial cable assembly composition is more complex, and has more strict process requirements, need to improve mature process technology and process, so choose RF coaxial cable assembly, as far as possible to choose the process technology is relatively leading manufacturers, Qiyuan microwave uses automated production line and advanced equipment, while selecting high-quality materials that can better meet the needs of excellent performance. For example, the use of low-density polytetrafluoroethylene (LD-PTFE) dielectric, silver-plated copper wire, so the RF coaxial cable assembly transmission loss is relatively low. Rf coaxial cable assembly machining accuracy is also high, but also the use of industry-leading compensation technology, significantly improve the performance of RF coaxial cable assembly. The inner conductor is made of copper material, the surface is free of impurities, and it is smooth and clean, the diameter tolerance is small, and the structure is stable, so the impedance performance of the cable is relatively strong.
For different use environment and use requirements, we can provide different series of test cable components, including ultra-low loss phase stabilization series, ultra-soft low loss phase stabilization series, high shielding/high temperature phase stabilization series, low loss flexible interconnection series, low loss power cable series, test/armored cable series.
