Precision Engineering for Reliable Connectivity

At the core of the KH-IPEX-SMAKWE-RG137-Q80MM RF adapter cable lies its meticulously engineered design and quality materials. The cable features high-grade RG137 coaxial cable as its transmission medium, with a finely tuned physical structure and shielding layer that forms a robust channel for high-frequency signals. This effectively resists external electromagnetic interference (EMI), ensuring exceptional signal clarity throughout the transmission path. The 80mm length is optimized for most compact devices—such as 5G micro base station modules, WiFi 6/6E network cards, drone transmission modules, and portable test equipment—offering flexible internal routing while minimizing inherent transmission loss, ensuring signal integrity.

Superior Electrical Performance Sets a New Benchmark

Electrically, the KH-IPEX-SMAKWE-RG137-Q80MM sets a new standard for miniaturized RF adapter cables. With an ultra-low conduction resistance (≤ 3.0 Ohm), the cable minimizes signal energy loss at the connectors—crucial for maintaining signal strength and improving system efficiency, especially in low-power applications. Additionally, its high insulation resistance (≥ 5.0M Ohm) significantly reduces leakage current between conductors and between conductors and external environments, ensuring safe and reliable operation even in humid or dusty conditions. The cable also offers robust withstand voltage performance up to DC 300V (10ms), providing strong protection against voltage surges and enhancing both system resilience and product lifespan.

Thoughtful Three-Piece Design for Flexible Integration

Kinghelm has ingeniously designed this solution as a three-piece set, not merely adding components but delivering unmatched adaptability. A single set covers diverse requirements in R&D, prototype testing, and production maintenance without the hassle of sourcing separate adapters. Whether connecting IPEX terminals (commonly used in compact network cards or built-in antennas) to standard SMA interfaces (used in testing equipment or external antennas), or functioning as an extension for test jigs, the three-piece design ensures plug-and-play convenience, significantly boosting work efficiency and reducing inventory complexity.
