  • RF connector and cable connection structure
    RF connector and cable connection structure Aug 08, 2022
        RF connectors used in communications, medical, aerospace and other fields are not just RF connectors, they are also used with cable assemblies to complete a signal bridge.      Generally, the RF connector has two forms of use: one is directly mounted on the instrument panel or the printed circuit board, and the other is a structure in which the RF coaxial cable is conn...

    About cable component loss values Aug 29, 2022
        A typical VSWR for a low-cost 3 GHz test cable and when used at higher frequencies requires a microwave test RF cable assembly, which means that the user has to pay a higher cost.      This is because the design and manufacturing philosophy of microwave cables is different from that of conventional cables. For example, microwave cables usually use multiple layers of sh...
  • Classification of RF coaxial connectors
    Classification of RF coaxial connectors Oct 09, 2022
        Due to the increasing variety of RF coaxial connectors, new structures and applications are emerging, and attempts to solve classification and naming problems with a fixed pattern have become difficult to adapt. The following is a list of some RF coaxial connectors sorted out .     1, according to the nature of use     External connector (for external chassis...
  • 5 points about RF connector signal interference solution
    5 points about RF connector signal interference solution Oct 17, 2022
        When the RF connector has a signal interference problem or cannot pass the test. The following five points of solution are summarized for your reference.     1) Although the chassis or cabinet is well shielded, the radiated emissions are too high or cannot pass the radiated immunity test. This is because the outer tow cable on the chassis or cabinet acts as an RF antenna. O...
  • Semi-rigid cable assembly electrical stability and low passive intermodulation
    Semi-rigid cable assembly electrical stability and low passive intermodulation Oct 24, 2022
        Semi-rigid cable assemblies have excellent passive intermodulation performance when equipped with suitable connectors, making them ideal for modern multi-frequency wireless communication systems including distributed antenna system related equipment. The following summarize the results  and the engineers explored.     Electrical stability:     Since the semi-...
  • Coaxial cable bending characteristics
    Coaxial cable bending characteristics Oct 31, 2022
        Many people mentioned the requirements for components (including electrical performance, flexibility, and use environment). The generalization is too idealistic. Because many requirements are actually contradictory to each other, it seems that the fish and the bear's paw can't have the same: for example, if you want the cable assembly to have a small difference and you want the cable...
  • Common PCB connector FD method loss test
    Common PCB connector FD method loss test Nov 13, 2022
        The signal transmission rate of high-speed interconnect links continues to increase. As a carrier for devices and signal transmission, the signal integrity of printed circuit board coaxial connector boards has a critical impact on the electrical performance of communication systems. Especially for the large-scale commercial use of 10G and 25G+ products, the monitoring of PCB connecto...
  • How coaxial cable works?
    How coaxial cable works? Nov 20, 2022
        Coaxial cable is also called RF cable. Coaxial cable refers to a cable with two concentric conductors, and the conductor and shield share the same axis. The most common coaxial cable consists of a copper conductor isolated from an insulating material. On the outside of the inner insulation is another layer of ring conductor and its insulator. The entire cable is then covered by a she...
