Series N RF Coaxial Connector, a classic medium-sized RF connecting component, features a precision threaded locking mechanism and rugged structure. Invented in the 1940s, it complies with MIL-C-39012, IEC 60169-16 and CECC 22210 standards, renowned for excellent electrical performance, high power capacity and strong anti-vibration capability, serving as a core interconnection part in harsh-environment and high-power RF systems.
The series boasts superior and stable electrical performance. It offers dual impedance options of 50Ω and 75Ω: 50Ω for high-power RF communication, radar and test systems (supporting DC to 11GHz, up to 18GHz for precision models), 75Ω for cable TV and broadcast applications. Key parameters are outstanding: VSWR ≤1.15 for straight types and ≤1.25 for right-angle types, contact resistance of inner and outer conductors ≤1mΩ, insulation resistance ≥5000MΩ, withstanding 1000V working voltage and 2500V withstand voltage, ensuring low-loss, anti-interference signal transmission.
Its unique advantages lie in threaded coupling and rugged design. The 5/8-24 UNEF thread ensures firm connection, effectively resisting vibration and preventing accidental loosening, while optional silicone O-rings provide IP67 waterproof and dustproof performance for outdoor use. Manufactured with high-quality materials, it adopts nickel-plated brass housing, gold-plated brass/beryllium copper contacts and PTFE insulators, withstanding -55℃ to +165℃ and 500+ plugging cycles.
Widely applied in 5G base stations, radar systems, satellite ground stations, power amplifiers, test instruments and outdoor communication equipment, it pairs with RG-58, RG-142 and 1/2-inch coaxial cables. As a mature, high-reliability solution, it remains a mainstream choice for high-power, harsh-environment RF interconnection, supporting stable signal transmission in industrial, aerospace and communication fields.
