Significance of Phase Stable Cable Development for the Whole System 

In order to ensure the precise positioning of aviation phased radar arrays, naval equipment, satellite tracking stations, electronic countermeasure systems, etc., the requirements for the RF coaxial cable matched above must be improved, and the phase stable cable was therefore born.
Compared with the ordinary RF cable, it obviously improves the frequency use range (0-110GHz), attenuation, standing wave and phase performance, etc.; compared with the current relatively high-end low-loss cable, it has the advantage of better phase stability.
I. The whole equipment requirements for phase stable cable is reflected in those aspects?
(a). Phase consistency requirements
For multiple cable assemblies of the same segment length and the same application frequency band, the electrical length is required to stay within the specified deviation, that is, the whole equipment needs a set of signals transmitted from the output part to the input part at the same pace, in order to do differential comparison analysis of the phase stable cable.

                            
What are the factors affecting the phase consistency of the phase stable cable assembly?
. Consistency of the mechanical length of the phase stable cable: for uniform phase stable cable, the mechanical length has a direct correspondence with the electrical length.
. Cable uniformity: poor uniformity of the phase stable cable can lead to large differences between the electrical and mechanical lengths, especially for longer phase stable cable assemblies with large mechanical length differences after phasing.
. The influence of the assembly process: assembly is the key link affecting the quality of the cable assembly, and the quality of assembly directly affects the consistency of the phase stable cable assembly. So this is the reason why the cost of the assembly requiring phase matching is high and the labor cost is greatly increased.
. The effect of bending or bending shape: When a group of assemblies are wired from different paths when in use, phase drift caused by different mechanical deformation will occur. If the bending shape changes a lot, the cable assembly itself is long, and the whole machine has high requirements for phase, on-site phase matching is required.

                                 
(ii). Time delay consistency requirements
There is a part of the whole equipment not only requires the signal transmission process phase to maintain consistent, the electrical length consistency requirements, but also the requirements of the cable assembly time delay. That is to say, there are requirements for the stability of the electrical length of the phase stable cable assembly. In this case, in addition to the several cases mentioned in (a) on the phase stable cable assembly impact, the temperature of the phase stable cable assembly can not be ignored.
Special reminder: for the production of phase stable cable, we do as a manufacturer to ensure that the consistency of the batch cable index is particularly important, because it is a prerequisite for ensuring the consistency of the assembly phase. ZOMWAVE provide phase stable cable with high performance and low price, we can ship out within 5 days with professional test report. Click blue words and learn more.
