As high-speed communication and wireless RF transmission become increasingly widespread, RF coaxial cables have become essential components for connecting antennas to motherboards, or linking modules together. Depending on the application scenario, frequency requirements, and connector types, RF cables are categorized into coaxial cables (e.g., RG series), miniature RF jumpers (e.g., IPEX, U.FL, MMCX interfaces), semi-rigid/semi-flex cables, and customized RF assemblies. Among them, the RG1.37 RF jumper cable stands out for its lightweight structure and stable performance, making it ideal for space-constrained electronic products such as wearables, Wi-Fi modules, Bluetooth modules, IoT devices, and drones.
