What is RF Antenna Cable Connector
With the integration of sensors into the RF antenna cable connector, a new 5G RF antenna cable connector suitable for 5g wireless connection is introduced. In order to implement wireless connection worldwide, the cost of customized components of 5G wireless equipment will be lower and the reliability should be further strengthened. The naming model of RF antenna cable connector is generally located by the internationally common main model, The structure form and model of different products shall be named according to the detailed standard specifications. How much do you know about the basis of RF antenna cable connectors?
RF Antenna Cable Connector Overview:
Coaxial connector (some people also call it RF antenna cable connector or RF antenna cable connector. In fact, strictly speaking, RF antenna cable connector is not completely equivalent to coaxial connector. RF antenna cable connector is classified from the perspective of connector use frequency, while coaxial connector is classified from the structure of connector. Some connectors are not necessarily coaxial, However, it is also used in the RF field, and the coaxial connector can also be used in low frequency. For example, the very common audio earphone plug, with a frequency of no more than 3MHz. From the traditional point of view, RF refers to the MHz category, and now the coaxial connector is often used in the microwave field. In the GHz category, the word "RF" has always been used, overlapping the word "microwave"), which is a branch of the connector, There are both commonalities and particularity of connectors. 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 guide), but also plays the role of shielding electromagnetic field (shielding the external interference of internal electromagnetic wave acts through the inner surface of the outer guide, and shielding the internal interference of external electromagnetic field acts through the outer surface of the outer guide), This feature gives the coaxial connector great space and structural advantages. The outer surface of the inner guide and the inner surface of the outer guide of the coaxial connector are basically cylindrical - in special cases, they are often required for mechanical fixation and have a common axis, so they are called coaxial connectors. Among several forms of transmission lines, coaxial cable is widely used because of its outstanding advantages (simple structure, high space utilization, easy manufacturing, superior transmission performance...), which leads to the demand for connecting coaxial cable, and coaxial connector is applied. Due to the advantages of coaxial structure, the continuity of characteristic impedance of (coaxial) connector (relative to other connectors) is easier to be guaranteed. Transmission interference and interference (EMI) are very low, transmission loss is small, and it is almost only used in RF and microwave fields. Because it is almost absolutely used in high frequency, it produces some electrical performance requirements different from other connectors
Application Field of RF Antenna Cable Connector
Consumer electronics products generally do not have high reliability requirements, because even if the product fails and may be restarted, it will be normal, but once the product fails in military products, medical products, automotive products, aviation products and important industrial equipment, the consequences will be serious. Therefore, coaxial connectors with higher reliability must be used in this situation
BNC is the earliest RF antenna cable connector. During World War II, due to the urgent need of war and the damage of various shipborne airborne electronic equipment, a large number of U.S. sea and air combat weapons were damaged to be repaired. In order to reduce the repair time, the U.S. Department of the Navy concentrated some excellent scientific researchers and engineers, In a relatively short period of time, it invented the fast plug - in and separation connector BNC (bayonets - Navy connector), which has become the originator of RF antenna cable connectors all over the world.
With the development of radar, radio and microwave communication, N, C, TNC and other series have emerged. After 1958, small products such as SMA, SMB and SMC have emerged. In 1964, the U.S. military standard Mil-C-39012 general specification for RF antenna cable connectors was formulated. Since then, RFC began to develop in the direction of standardization, serialization and generalization. Therefore, the earliest development began from the military engineering department
Therefore, the United States is the largest manufacturer and consumer of general-purpose RF antenna cable connectors in the world. Of course, its technical level is also first-class; Therefore, the U.S. military standard mlc39012 is considered to be the highest standard of RF antenna cable connector; The standards of other advanced countries include German DIN, British BS, Japanese JIS and IEC standards; Most of these national or international standards are formulated with reference to or equivalent to the U.S. military standard, and some countries or companies even directly apply the U.S. military standard
