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 parts for 5G wireless devices will be lower in the future and reliability It should be further strengthened. The naming model of the RF connector is generally located by the internationally used main name model. The naming model of the structure of different products should be formulated in accordance with the detailed standard specifications. How much do you know about the basics of RF connectors?

RF Coaxial Connectors

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 radio frequency 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 radio frequency field. Coaxial connectors can also be used in low frequencies, for example, very common audio Headphone plug, the frequency does not exceed 3MHz. From a traditional point of view, radio frequency 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 wire and the outer conductor is not only the ground wire of the signal wire (reflected on the inner surface of the outer conductor), but also plays a role in shielding the electromagnetic field (shielding the internal electromagnetic waves from the outside The interference acts on the inner surface of the outer conductor, and the shielding of the external electromagnetic field from the internal interference acts on the outer surface of the outer conductor.

This feature gives the coaxial connector a lot of space and structural advantages. The outer surface of the inner conductor of the coaxial connector and the inner surface of the outer conductor are basically cylindrical-special cases are often required for mechanical fixation and have a common axis, so they are called coaxial connectors.

RF Coaxial Cables

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…), the coaxial connector 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, some electrical performance requirements are different from other connectors.

Due to the development of electronic components, RF coaxial connectors have many good performance. Elecbee.com is a store which sell many kinds of electronic products.
