Standard Specification For Cable Assembly
- Sep 14, 2017 -

     The correct selection of RF cable components in addition to the frequency range, standing wave ratio, insertion loss and other factors, but also consider the mechanical characteristics of the cable, the use of the environment and application requirements, in addition, the cost is also a constant factor.Cable Assembly

    RF coaxial cable is used to transmit RF and microwave signal energy. It is a kind of distributing parameter circuit, its electric length is the physical length and the transmission speed function, this and the low-frequency circuit has the essential difference. RF coaxial cable is divided into half, half soft flexible cables three kinds, different applications should choose different types of cable. Semi-rigid and semi-flexible cables are generally used in the interconnection of equipment, while flexible cables should be used in the field of testing and measurement.Cable Assembly

    This kind of cable is not easy to be bent easily, the outer conductor is made of aluminum tube or brass tube, its RF leakage is very small (<-120db), the signal crosstalk in the system can be neglected. The passive intermodulation characteristics of this cable are also ideal. If you want to bend to a certain shape, you need a special molding machine or a handmade abrasive to complete it.Cable Assembly

     So troublesome processing technology in exchange for a very stable performance, semi-rigid cable using solid PTFE material as a filler medium, this material has a very stable temperature characteristics, especially at high temperature conditions, with very good phase stability. The cost of semi-rigid cable is higher than that of semi flexible cable, and it is used in a variety of RF and microwave systems.Cable Assembly
