N M Solder for SM250 Cable

Description

The N-Type 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. These cables are used in applications requiring maximum shielding effectiveness and precise phase tracking. The connector’s design allows for a seamless transition from the connector interface to the cable’s solid outer conductor, minimizing signal leakage and reflection.

This connector utilizes a direct-solder termination for both the center conductor and the outer body. By soldering the cable’s copper jacket directly to the connector body, the assembly achieves an airtight, 360-degree electrical bond that is superior for maintaining Passive Intermodulation (PIM) stability and low VSWR. Manufactured with a durable nickel or tri-metal 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

• Superior Shielding Effectiveness: The solder-on body interface creates a continuous metallic shield, providing maximum protection against EMI/RFI interference in sensitive microwave systems.

• High Phase Stability: Optimized for semi-rigid SM250 cable, ensuring stable phase characteristics and low signal delay, which is critical for beamforming and radar applications.

• Precision SM250 Match: Specifically calibrated for the 0.250-inch OD solid jacket, ensuring an optimized electrical transition and high mechanical rigidity.

• Airtight Mechanical Bond: The direct-solder assembly method ensures a moisture-proof and permanent connection that resists oxidation and environmental degradation.

• Microwave Grade Performance: Features high-conductivity materials and gold-plated contacts to maintain signal integrity and low VSWR across high-frequency bands.
