N M Solder for Semi-rigid .141/RG402 Cable

Description

The N-Type connector is one of the most widely used high-performance RF interfaces, known for its ability to handle high power levels and maintain low signal loss at microwave frequencies. This male (plug) variant is specialized for the 3.58mm (0.141″) semi-rigid cable class, including RG402. Because semi-rigid cables utilize a solid copper outer conductor, this connector employs a direct-solder termination method, creating a seamless, airtight mechanical and electrical bond that is far superior to standard crimp designs in high-frequency applications.

By eliminating the crimp ferrule, this solder-on plug provides maximum EMI shielding and minimizes signal leakage. The design ensures a phase-stable connection, making it essential for precision microwave sub-systems, laboratory test leads, and satellite communication links where signal purity and low VSWR are critical. 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

• Optimized for RG402/0.141″: Precision-machined bore diameter designed specifically for the solid outer jacket of semi-rigid cables, ensuring a perfect fit and a clean, repeatable soldering process.

• Direct-Solder Integrity: The solder-on body design creates a permanent, 360-degree electrical path that significantly reduces insertion loss and VSWR compared to mechanical terminations.

• Rugged Threaded Coupling: The 5/8-24 threaded interface provides a secure, vibration-proof connection with high torque capability, ensuring stable performance in outdoor and industrial environments.

• Superior EMI/RFI Shielding: The solid-to-solid solder connection provides a highly shielded transition, critical for sensitive microwave circuits and high-frequency data transmission.

• High-Power Handling: Precision-engineered to support higher power levels and frequencies up to 18 GHz with exceptional stability, suitable for modern telecommunications and aerospace infrastructure.
