Over the years there has been a huge development in the line of cable assemblies. Coax Cable assembly is the most abundant cable used for signal and power transmission. With the rise in technology, the coaxial cable assemblies have also increased its performance, limitations, and sustainability.Coax Cable assembly can be produced to a variable diameter size of 0.05 inch to 1.40 inch with minimum insertion losses. The ability of Coax Cable Assembly to be flexible, compatible and the advantage to be customized relative to the design makes it higher in production rather than other types of cable assemblies.
Coaxial Cable provides greater compatibility with the connectors and provides the best combination of cable and connector characteristics. Whether the connector is high volume or small volume the cable provides excellent compatible specifications regarding the design.
Following are two very important data precision tests which most of the cables undergoes in their post production assessment tests.
1. Voltage Standing Wave Ratio (VSWR)
Voltage Standing Wave Ratio involves the analysis of standing wave ratio of the Coax Cable assembly. It is actually a comparison of impedance matching among the transmission cable carrying radio signal which needs to be transmitted using an antenna. Impedance matching is essential to transfer the maximum amount of load from the transmission line to the load line. The easiest way to achieve this is to make the load resistive throughout the transmission for that it is essential that there should be no capacitive or inductive influence while loading transmission. If an ideal power factor is achieved it could eliminate the inductive and capacitive part from the impedance leaving only the resistive part.
2. Insertion Losses
Insertion losses in coaxial cable assemblies are of three major types which are discussed as follows.
- Reflected losses are the losses which are caused by the VSWR of the connectors.
- Dielectric losses are the losses which are caused by the power losses of the dielectric medium.
- Copper losses are the losses which are caused by power losses due to conducting surfaces.
