Series L29(7/16) RF Coaxial Connector is a large-size, thread-connected RF connecting component, also known as DIN 7/16 connector, manufactured in compliance with IEC 169-4 and DIN 47223 standards. Characterized by rugged structure, high power capacity and excellent waterproof performance, it is specially designed for medium and high-power signal transmission, serving as a core interconnection part in outdoor and harsh-environment RF systems.
The series boasts outstanding electrical and mechanical performance tailored for practical needs. With a fixed characteristic impedance of 50Ω, it supports a working frequency range of DC to 7.5GHz, perfectly adapting to microwave transmission and mobile communication scenarios. Key electrical parameters are excellent: insertion loss is extremely low, VSWR is controlled within ≤1.2 for straight types and ≤1.3 for right-angle types, contact resistance of inner conductor ≤1.0mΩ and outer conductor ≤0.5mΩ, while insulation resistance is ≥1000MΩ, ensuring stable and low-loss signal transmission.
Its prominent advantages lie in high power capacity, waterproof structure and strong vibration resistance. Most models are equipped with silicone rubber sealing parts, enabling reliable waterproof performance for outdoor use, while the M29×1.5 metric thread connection ensures firm mating and resistance to harsh environmental interference. Manufactured with high-quality materials, it adopts brass housing (plated with nickel, silver or ternary alloy), beryllium copper or tin-phosphorus bronze contacts (gold or silver plated), and PTFE insulators, enhancing corrosion resistance and mechanical durability, withstanding 500+ plugging cycles and a working temperature range of -40℃ to +85℃.
Widely applied in mobile communication base stations, radar systems, microwave transmission equipment and outdoor RF devices, it is especially suitable for high-power transmission lines in outdoor environments. As a cost-effective and reliable interconnection solution, it plays an indispensable role in the stable operation of communication and microwave systems, supporting the efficient transmission of medium and high-power RF signals.
