SMA connector

The SMA female to SMB plug adapter is a highly sought-after solution for connecting RF coaxial cables. This adapter features a reliable threaded coupling design, ensuring high mechanical strength and durability. With excellent electrical properties, it is ideal for use in mobile communication equipment and electronic communication instruments. The interface dimensions and technical specifications align with MIL-C-39012, IEC 169-15, and CECC 22110 standards, guaranteeing optimal performance in various applications.

The SMA female to SMB plug adapter is a versatile connector designed for RF and microwave applications, facilitating seamless interconnections in electronic systems operating at frequencies up to 18 GHz and beyond. This adapter combines the reliability of the SMA connector with the compact design of the SMB interface, making it ideal for tight layouts where space is at a premium.

The SMA connector, known for its semi-precision miniature design, comes in various forms, including male, female, straight, right angle, bulkhead, flange, front mount, and rear mount. The typical coupling mechanism is threaded, featuring a hexagonal nut that should be securely tightened using a torque wrench to ensure a proper connection. This adaptation enhances system flexibility while maintaining performance integrity.
