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.
