How to define the bend radius of Phase Stable Cable?

ZOMWAVE's Phase Stable Cable products have a high volume of shipments every month, so our engineers often communicate with our customers and find that many of them mention the requirements of coaxial cable assemblies including electrical performance, flexibility, and usage environment, etc. The general overview is too big to be idealized. This is because many of the requirements are in fact in conflict with each other, just as the fish and the bear's paw cannot be combined. For example, if you want to make Phase Stable Cable product loss is small, but also want Phase Stable Cable bending radius is very small, there is definitely a contradiction, the main reason is that the cable loss is inversely proportional to the outside diameter of the cable. The following ZOMWAVE engineers will talk about the bending characteristics of coaxial cable.

For those Phase Stable Cable products that are more common in the laboratory, its bending characteristics can ensure the accuracy of the test, because the bending of Phase Stable Cable will cause VSWR, loss and phase changes.

The vast majority of Phase Stable Cable products have a minimum bending radius requirement, which is divided into two types of static and dynamic bending radius. For example, the U.S. military standard RG223/U cable, the minimum allowable static bending radius of 30mm, the minimum dynamic bending radius is 54mm. in the actual test applications, it is recommended that the minimum bending radius of the cable should not be less than 10 times its diameter. ZOMWAVE provide Phase Stable Cable with high performance and low price.
