How Much Do You Know About the Basics of RF Connectors?


With the integration of RF coaxial connectors with sensors, a new type of 5G RF connector suitable for 5G wireless connections has been launched. In order to implement wireless connections on a global scale, the cost of customized components for 5G wireless devices will be lower in the future and reliability It should be further strengthened. The naming model of radio frequency connector is generally located by the main name model commonly used in the world. The structure naming model of different products should be formulated in accordance with detailed standards. How much do you know about the basics of RF radio frequency connectors?

RF Coaxial Connector

Overview of RF coaxial connectors:

Coaxial connector, (some people also call it a radio frequency connector or RF connector, in fact, strictly speaking, the radio frequency connector is not completely equivalent to the coaxial connector. The radiofrequency connector is from the perspective of the frequency of the connector. Coaxial connectors are classified from the structure of the connector. Some connectors are not necessarily coaxial, but they are also used in the radiofrequency field. Coaxial connectors can also be used in low frequencies, for example, a very common audio Headphone plug, the frequency does not exceed 3MHz. From a traditional point of view, radiofrequency refers to the MHz category. Nowadays coaxial connectors are often used in the microwave field. In the GHz category, the term "radio frequency" has always been used, overlapping with the "microwave" one above the word) is a branch of the connector, which has the commonality of the connector and its particularity. The coaxial connector has 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 wire of the signal line (reflected on the inner surface of the outer conductor) but also plays the role of shielding electromagnetic fields (shielding internal electromagnetic waves to external interference through the inner surface of the outer conductor, shielding external electromagnetic fields to internal interference through the outer surface of the outer conductor), which gives coaxial connectors great space and structural advantages. The outer surface of the inner conductor of the coaxial connector The inner surface of the outer conductor and the inner surface are basically cylindrical-special cases are often required for mechanical fixing and have a common axis, so they are called coaxial connectors. Among the several forms of transmission lines, coaxial cables are commonly used due to their outstanding advantages (simple structure, high space utilization, easier manufacturing, superior transmission performance...) to connect coaxial cables. The demand for cables, the application of coaxial connectors was born. 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 guaranteed, the transmission interference and interference (EMI) are very low, and the transmission loss is almost unique. The ground is used in radio frequency and microwave fields. And because it is almost absolutely used at high frequencies, it produces some electrical performance requirements that are different from other connectors.
