N M Solder for Semi-rigid .086/RG405 Cable

Description

The N-Type connector is a staple in high-frequency engineering, valued for its durability and excellent microwave performance. This male (plug) variant is specialized for the 2.18mm (0.086″) semi-rigid cable class, including RG405. Because semi-rigid cables utilize a solid copper outer conductor, this connector employs a direct-solder termination method. This creates a permanent, airtight mechanical and electrical bond that provides superior performance compared to mechanical crimping for small-diameter microwave lines.

By eliminating the crimp ferrule and soldering the cable’s outer jacket directly to the connector body, this plug ensures maximum EMI shielding and minimizes signal leakage. The design provides a phase-stable connection, which is critical for precision instrumentation, satellite communication systems, and cellular infrastructure where low VSWR and signal purity are required. Manufactured with a heavy-duty nickel or silver-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation up to 18 GHz.

Key Technical Advantages
