This cable features an IPEX MHF I (first generation) connector on one end and a gold-plated SMA female connector on the other, making it widely applicable to WiFi modules, Bluetooth antennas, 4G/5G communication modules, drone remote control systems, GPS antennas, and wearable smart devices. Whether for RF development board testing or embedded module integration, the Kinghelm KHB(RG113)-55-29 ensures consistent and dependable signal connectivity.

The product utilizes a high-precision imitation IPEX connector with gold plating for enhanced oxidation resistance and superior electrical conductivity. On the output end, a standard SMA female jack with a split-type inner socket and 11-thread design provides broad compatibility with most commercial SMA RF devices. Secure connections at both ends result in minimal signal loss, maintaining excellent transmission quality even under frequent mating or vibration conditions.

The entire cable is constructed with high-performance RF1.13 coaxial cable in black, with an ultra-thin 1.13mm outer diameter. This provides outstanding flexibility, ideal for compact device interiors where space constraints demand agile routing. A black heat-shrink tube (OD: 2.0mm) is applied at the solder joints for reinforced strain relief, protecting the connection from mechanical stress, wear, and EMI, thereby enhancing both durability and aesthetics.

With a length of 55mm, this cable is precisely tailored for short-distance high-frequency connections. Compared to standard-length cables, this compact design significantly reduces signal attenuation and improves integrity—especially suited for internal links between PCBs and antennas. Weighing just 3.79g per unit, it is lightweight and easy to handle, making it suitable for both prototyping and mass production assembly.

The KHB(RG113)-55-29 comes in a five-piece pouch packaging, offering convenience for engineers during prototyping, testing, and small-batch integration. The compact, protective packaging also shields connector interfaces from dust and mechanical damage, extending product lifespan. Each unit reflects Kinghelm's dedication to high-quality craftsmanship and is a trustworthy core component for advanced electronics and RF communication systems.

In real-world applications, whether for consumer electronics antenna routing or industrial-grade RF transmission, the KHB(RG113)-55-29 delivers consistently low-loss and stable connections. It is particularly well-received in cutting-edge sectors such as UAVs, smart homes, automotive GPS systems, and IoT terminals, where its flexible deployment, wide compatibility, and effective shielding provide distinct advantages.
