N F Solder for SM250 Cable

Description

The N-Type female connector is prized for its exceptional mechanical strength and stable performance across the microwave spectrum. This variant is specialized for the 6.35mm (0.250″) cable class, specifically optimized for SM250 (Semi-Rigid) and RG401 equivalent cables. As a female interface (jack), it is frequently used to provide a high-precision mounting point on chassis or as a stable receptacle for semi-rigid internal jumpers that require maximum shielding and minimal signal leakage.

This connector utilizes a direct-solder termination for both the center conductor and the outer body. By soldering the cable’s solid copper jacket directly to the connector body, the assembly achieves an airtight, 360-degree electrical bond. This method is superior for maintaining Passive Intermodulation (PIM) stability and ensuring the lowest possible VSWR in high-frequency applications. Manufactured with a durable tri-metal or gold-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and exceptionally low attenuation up to 18 GHz.

Key Technical Advantages
