Micro RF Coaxial Connectors, some people also call it RF connectors or RF connectors, in fact, strictly speaking, RF connectors are not exactly the same as coaxial connectors, RF connectors are classified from the perspective of the frequency of use of connectors and coaxial connectors are classified from the connector structure, some connectors are not necessarily coaxial, but also used RF connectors can also be used in low frequency, for example, very common audio headset plug, the frequency does not exceed 3MHz. From the traditional point of view, RF refers to the MHz category, now the coaxial connectors are often used in the microwave field, GHz category, the word "RF" has been used, overlapping on the word "microwave". The term "RF" has always been used, overlapping the term "microwave", and is a branch of connectors that has the commonality and specificity of connectors.

Micro RF Coaxial Connectors have an inner conductor and an outer conductor, the inner conductor is used to connect the signal line and the outer conductor is not only the ground of the signal line (reflected in the inner surface of the outer conductor, but also plays a role in shielding electromagnetic fields (shielding internal electromagnetic waves to external interference through the inner surface of the outer conductor to play a role in shielding external electromagnetic fields to internal interference through the outer surface of the outer conductor) This feature gives the coaxial connector great space and structural advantages. The outer surface of the inner conductor and the inner surface of the outer conductor of a coaxial connector are essentially cylindrical - a special case is often required for mechanical fixing - and have a common axis, hence the name coaxial connector. Among several forms of transmission lines, Micro RF Coaxial Connectors are commonly used due to their outstanding advantages (simple structure, high space utilization, easier manufacturing, superior transmission performance...) The need for connecting coaxial cables has arisen due to the widespread adoption of coaxial connectors. Due to the superiority of the coaxial structure, the continuity of the characteristic impedance of the (coaxial) connector (compared to other connectors) is more easily ensured, the transmission interference and interference (EMI) is very low, the transmission loss is low and it is almost exclusively used in the field of RF and microwave. Because of the almost absolute use in high frequencies, there are some electrical requirements that are different from other connectors.

Application areas of Micro RF Coaxial Connectors.

Consumer electronics products are generally not so high reliability requirements, because even if the product failure may restart on normal, but military products, medical products, automotive products, aviation products, important industrial equipment, the above applications once the product failure, the consequences are serious, so this occasion must use the higher reliability of Micro RF Coaxial Connectors.
