Cable assembly manufacturers share the indicators to be considered in selecting RF cable assemblies

It is well known that a wide variety of cable assemblies are widely used in the communications industry, including RF cable assemblies produced by cable assembly manufacturers. The RF cable assembly is mainly composed of four parts: the conductor, the outer conductor and the sheath. Although the combined parts are roughly the same, the performance of different RF cable assemblies is not the same, mainly because of their different indicators. So what are the indicators to consider when choosing RF cable assemblies? The following cable assembly manufacturers share one by one:

1. Characteristic impedance

In the view of professional cable assembly manufacturers, the characteristic impedance is an important indicator to measure the RF cable assembly, and it is also one of the frequently mentioned indicators. Because the transmission power and signal reflection of the RF cable assembly depend on the matching degree of its characteristic impedance with other components. If perfectly matched, the loss of the cable is only the attenuation of the transmission line and there is no reflection loss. Judging from the current situation, cable assembly manufacturers have found that most of the RF cable assemblies used in the field of communications are similar.

2. Standing Bobby

Cable assembly manufacturers emphasize that the selection of RF cable assemblies also need to check their standing wave ratio, which is the loss of their callback. Because the impedance of the RF cable will change, it will cause the reflection of the signal, which will lead to the loss of the incident wave energy, which can also be one of the indicators to measure the performance of the cable assembly.

3. Average power capacity

The average power capacity refers to the capacity of the cable to consume heat energy generated by the dielectric and resistance losses. In actual application, the effective power of the cable is related to the standing wave ratio, temperature and height. Therefore, the cable assembly manufacturers with good sales volume in the industry emphasize that the average power capacity should also be considered when selecting the cable assembly.

In addition, cable assembly manufacturers with good sales in the industry suggest that when selecting RF cable assemblies, they should also consider comprehensively according to their propagation speed, phase stability during bending, attenuation and other indicators, so as to ensure a better use experience when actually using RF cable assemblies.
