Stability and Factors of Phase Stable Cable Assemblies

The most characteristic indicator of Phase Stable Cable Assemblies is phase stability. It is the amount of change in the electrical length of the cable assembly when its own and environmental conditions change. Phase Stable Cable Assemblies are the magnitude of the change in the electrical length of the cable assembly when the phase of the signal at the input is regulated and the magnitude of the change in the output phase.

The following is a list of catalogs:

Electrical Length

Dielectric inhomogeneity

Electrical Length

The electrical length is the determining factor for the phase of the assembly. To make the Phase Stable Cable Assemblies of N units (N≥2) have consistent phase, it is necessary to make them have consistent electrical length, insulation dielectric constant, ambient temperature and cable bending, etc. Under the ideal dielectric state and the same ambient temperature and bending conditions, if the mechanical length of the cable can be guaranteed to be consistent, it is possible to ensure consistent electrical length.

Dielectric inhomogeneity

But in Phase Stable Cable Assemblies in the manufacturing process, there is an unavoidable media inhomogeneity. This inhomogeneity is both the insulation material itself, such as impurities containing air holes, but also the cable media structure, the manufacturing process, and other factors. Therefore, only ensuring consistent mechanical length can not completely ensure the consistency of the electrical length of the period, the longer the component length of this phase inconsistency month obvious, but also need to use the electrical length test means to assist processing.

Because of the rigidity of Phase Stable Cable Assemblies, some cable assemblies are very stiff and difficult to install. Flexible microwave cables have excellent electrical properties and are assembled using proprietary technology to minimize voltage standing wave ratio (VSWR) and insertion loss, resulting in an excellent cable and connector combination. Industrial applications require Phase Stable Cable Assemblies with high performance and a variety of connector options.

At the same time, the cable assembly itself changes when in bending, twisting, mechanical deformation, the transmission of power signals generated by their heat temperature changes, etc. And the environmental conditions will change due to changes in dielectric material dielectric constant, material thermal expansion coefficient mismatch caused by structural dimensional changes, stress changes, etc. The actual electrical length of the cable assembly will also change accordingly due to changes in the dielectric material dielectric constant. The changes in structure size are due to a mismatch of material thermal expansion coefficient, and also in stress, which will cause phase changes.

It is the responsibility of each manufacturer to produce a Phase Stable Cable Assemblies that meets the standards, to ensure the safety of its supply and the healthy development of the Phase Stable Cable Assemblies market.
