SMA connectors are a type of mini coaxial connectors designed according to the standard of MIL-C-39012, IEC 60169-15 and CECC 22110/22111. These products are of thread connecting mechanism and high frequency and can provide the broadband from DC to 18GHz and are characterized by low-frequency reflection and an impedance of 50Ω. The main features of this series are high mechanical strength, high durability and low-voltage VSWR. They are of long span, superior performance and high reliability and can be widely used to connect RF coaxial cables or micro-wave in the RF circuits of base stations, cable assemblies, components, instruments and meters, military use, computer procedure control and digital communications equipment.
