This high-performance coaxial cable assembly supports a 0-6 GHz frequency range with SMA-Male and N-Male connectors and a standard 50Ω impedance. Constructed with a silver-plated brass inner conductor, PTFE insulator, and tinned copper braided outer conductor, it offers an insulation resistance of ≥1500 MΩ/Km and a withstand voltage of 3000V rms/min. From 500 MHz to 8000 MHz, it delivers low attenuation (0.27~1.39 dB/m) . Operating reliably from -45°C to +125°C, this cable combines low loss, high voltage resistance, and superior environmental adaptability, making it an ideal interconnect solution for telecom, radar, and test & measurement systems.
