The SMA RF connector (SubMiniature version A) is a widely used coaxial connector designed for high-frequency RF and microwave applications. Featuring a precision threaded coupling mechanism, SMA connectors provide secure mating, low signal loss, and excellent electrical performance. Standard SMA connectors are designed with 50-ohm impedance and typically support frequencies up to 18 GHz, with higher-performance variants available for extended ranges.
SMA connectors are commonly used in antenna systems, wireless communication equipment, RF modules, test instrumentation, satellite communication, and industrial electronics. Their robust mechanical design ensures excellent vibration resistance and long-term reliability in demanding environments.
RunGu Enterprise offers OEM/ODM manufacturing services for SMA connector metal components, including precision CNC turning, fine threading, and tight tolerance control. Materials such as stainless steel, brass, and copper alloys are available, along with surface treatments like gold plating and nickel plating to enhance conductivity and corrosion resistance.
