The N-type series RF coaxial connector is a RF coaxial connector with a threaded connection mechanism developed and produced in accordance with the US military standard MIL-C-39012. It has the characteristics of wide bandwidth, good shock resistance, high reliability, and excellent performance, and is widely used in microwave communications and measurement systems. The characteristic impedance of the N-type series RF coaxial connector produced by our factory is divided into two types: 50Ω and 75Ω.
Main Technical Specifications:
◆ Characteristic Impedance: 50Ω/75Ω
◆ Frequency Range: DC-18GHz(50Ω)/DC-3GHz(75Ω)
◆ Insulation Resistance: ≥5000MΩ
◆ Dielectric Withstand Voltage: 1500V(rms)
◆ Voltage Standing Wave Ratio (VSWR): ≤1.30
◆ Mating Cycles: 500 times
