This product features a gold-plated right-angle SMA connector with an external thread and inner bore structure, paired with a black RG1.13 high-frequency coaxial cable. With a total length of 200mm, it supports a maximum DC voltage of 100V (10ms), a conduction resistance ≤3.0 ohm, and an insulation resistance ≥20M ohm, ensuring excellent signal stability and anti-interference performance for both industrial and consumer-level high-frequency connection demands.

The KH-IPEX-SMA-W-200 is designed for durability and compact integration. Its right-angle SMA connector allows flexible deployment in tight spaces, reduces the risk of breakage, and supports easy plug-and-play operation. The SMA interface is precisely CNC-machined and gold-plated for superior oxidation resistance and lower contact resistance, ensuring stable connections and optimal signal integrity. The IPEX end delivers secure, reliable connections with refined craftsmanship, and is widely compatible with mainstream RF modules from Quectel, SIMCom, Fibocom, Neoway, Gosuncn, and more.

The cable uses black RG1.13, offering greater flexibility and resistance to bending compared to standard coaxial cables—ideal for dynamic and bend-intensive environments. Its low signal loss at high frequencies and excellent EMI suppression ensure clean, reliable long-distance transmission, making it a crucial component for stable RF communication systems. The 200mm length balances routing flexibility with neat cable management, enhancing overall device aesthetics and integration.
