High-frequency cables, also known as high-frequency coaxial cables, are special cables designed for transmitting high-frequency radio frequency signals, with a standard characteristic impedance of 50Ω or 75Ω. They are capable of carrying GHz-level high-frequency electrical signals, solving the problems of signal attenuation, electromagnetic interference and signal distortion that plague ordinary wires in high-frequency scenarios. They are widely used in high-speed signal transmission, wireless communications, RF testing, high-definition video transmission and other fields.

1. Basic Internal Structure

• Inner ConductorMade of high-purity copper or silver-plated copper with excellent conductivity, reducing high-frequency signal loss and ensuring transmission speed.
• Dielectric Insulation LayerConstructed with low-dielectric materials such as foamed PE and PTFE (Teflon), to reduce signal reflection and attenuation and stabilize impedance.
• Shielding LayerAvailable as single-layer aluminum foil, braided copper mesh, double-layer composite shielding and other structures. It blocks external electromagnetic interference and prevents internal signal leakage, improving signal purity.
• Outer JacketMade of wear-resistant and weatherproof materials such as PVC and LSZH (Low Smoke Zero Halogen), protecting the internal structure with properties of bending resistance, wide temperature tolerance, moisture resistance and corrosion resistance.

2. Core Performance Features

• Precise and Stable ImpedanceStrictly controlled 50Ω/75Ω standard impedance, avoiding signal reflection, disconnection and distortion during high-frequency transmission.
• Low Signal AttenuationOptimized dielectric and conductor materials for high-frequency bands to maintain low loss over long distances, ideal for high-speed and long-haul signal transmission.
• Superior Anti-Interference PerformanceMulti-layer shielding suppresses EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference), preventing signal degradation caused by nearby circuit boards and power cables.
• High Transmission SpeedSupports high-frequency, high-speed signals for high-speed digital data, RF antenna connections and high-definition audio-video transmission.
• Durable and Easy to RouteUltra-fine flexible versions allow bending for tight internal device installations and withstand repeated long-term flexing.
