SMA Plug Kit for RG-405 Semi-Rigid Coax
The 1050548-1: Rated at 50 Ohms impedance and 18 GHz maximum frequency, it covers the full SMA bandwidth for test equipment, microwave modules, and antenna feeds. The gold-plated stainless steel body with gold center contact (beryllium copper) gives corrosion resistance and consistent RF performance over 500 mating cycles.
Cable Prep and Assembly
This kit is built for RG-405 (.085" diameter) semi-rigid coax — the standard cable for SMA pigtails and module interconnects. Both the shield and the center contact are solder-terminated, so assembly requires a soldering station and a cable prep tool to square-cut the outer conductor and strip the dielectric to the correct length. The PTFE insulator centres the contact; the threaded body couples to any standard SMA jack. No crimp tool is needed, which makes this a practical choice for low-volume builds or field repairs where a crimp die set isn't available.
