Frequency Range Of Cable Assembly
- Sep 26, 2017 -

      Coaxial cables are one of the most frequently overlooked components of the system, unless they fail. Microwave cable Assemblies do not add any effect when they are in optimal condition: no loss, no phase distortion. When it is in its worst condition, the cable loss can become so severe that it must be compensated with a broadband amplifier circuit. The coaxial cable and cable assemblies used to test and measure applications must be "invisible" to the system in order to make their electrical properties not measured as part of the characteristics of the equipment to be tested (DUT).Cable Assembly

      Although the automated test equipment (ATE) system usually uses semi-rigid cables, and the DUT can be automatically placed in the appropriate test fixture, many measurement systems based on the microwave Vector Network Analyzer (VNA) need to connect the DUT to the test system port through a flexible cable component.Cable Assembly

      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. 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. Cable Assembly

      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

     If you want to bend to a certain shape, you need a special molding machine or a handmade abrasive to complete it. 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
