Two, SMA RF coaxial connector General description: SMA series is a widely used small threaded coaxial connector, it has a frequency bandwidth, excellent performance, high reliability, long life characteristics. Suitable for the microwave equipment and digital communication system connecting the RF cable RF circuit or microstrip line. SMA series is a widely used small threaded coaxial connector connected. SMA series of central conductors and insulators fixed capture type commonly used to obtain a sufficiently low VSWR. SMA series with inch threaded connections, high strength, good shock resistance. Direct contact with the end face of the outer conductor, the insertion loss to a minimum. Compared to other types of connectors, SMA series with a small, low VSWR characteristics. Adopt appropriate adapter cable, SMA connector at 18GHz still have good electrical properties. Specially processed connector, which can be achieved using a frequency of 25GHz. SMA series long life, superior performance and high reliability. Widely used in microwave devices and digital communication devices to connect the RF coaxial cable RF circuit or microstrip. Three, SMA RF coaxial connector Technical parameters: Main technical characteristics TECHNICAL CHARACTERISTICS Temperature range Temp.range -65 ~ + 165 ° C (PE Cable -40 ~ + 85 ° C) Characteristic impedance Impedance 50Ω, 75Ω Frequency Range Frequency Range DC ~ 4GHz (50Ω); 0 ~ 2GHz (75Ω) Operating voltage Working Voltage 335V max (RMS) voltage Withstand Voltage 1000V rms (minimum sea level) within the contact resistance between the conductors Contact resistance Center Contact ≤ 6 mΩ outer conductor between Outer Contact ≤ 1 mΩ Insulation resistance Insulation resistance ≥ 1000 MΩ VSWR VSWR Straight Straight ≤ 1.25 Right angle ≤ 1.45 curved durability Durability (mating) ≥500 times (cycles) materials and coating MATERIAL & PLATING shell body shell brass gold plated brass gold plated brass pin contact pin brass gold plated beryllium gold plated jack socket, gold plated beryllium gold plated elastic contact elastic contact beryllium gold plated beryllium gold plated insulator insulator polytetrafluoroethylene fluoro ethylene PTFE crimping suite crimp ferrule copper alloy nickel or gold-plated copper alloy nickel or gold plated o-ring sealing silicone rubber o-ring sealing 6146 silastic use technical standards APPLICABLE STANDARD MIL-C-39012; CECC 22130; IEC 60169-10 The interface dimensions INTERFACE MATING DIMENSIONS four Durso SMA RF connector: SMA Durso products are produced by gold plating, standards to common standards, environmental protection levels. Is the quality of the product first. For the majority of wireless AP, antenna manufacturers to use. Due to the special nature of the product, we accept SMA product samples to map custom. Trying for customers to produce quality products. We welcome the advisory. Durso SMA connectors are designed to adapt to the design of high-performance microwave frequency subminiature connector. Threaded engagement ensures a uniform external conductor contacts, so that the SMA environment at higher frequencies to minimize reflections and attenuation, while providing excellent mechanical strength and durability. SMA connector can operate at up to 50 Ohm and 18 GHz, to ensure high mechanical strength and durability, ideal for high-speed wireless applications. Ultra-compact design vertical mating threaded engagement space-efficient connector does not ensure the separation of wireless and GPS applications ideal choice to provide a non-magnetic modules are available for medical applications in high vibration applications
