How to use RF connectors correctly and its main characteristics?

When using RF connectors, they must be used and stored correctly to avoid unnecessary troubles. When receiving the RF connector, we should carefully observe the outer packaging to see if there is any obvious damage, and whether there will be any damage to the connector itself, etc. We must ensure that the connector we see is intact, so that it will not affect our use of the connected machine. When the RF connector is not in use for the time being, don't place the connector at will, especially in a sunny place. If you forget to place it because of negligence, the connector will be damaged in quality due to long-term sunlight exposure, thus affecting its use, and even safety accidents will occur. It is not allowed to place the RF connector in a high temperature place. Continuous high temperature or high humidity will damage the connector, especially in an environment with chemicals, and the connector will be corroded, so that the outer metal protective layer will lose its protective function. When you need to move the connector, don't panic. Be careful to prevent the connector from touching hard objects and causing damage to the connector. Don't put it under heavy objects to avoid crushing the connector. Another enemy of radio frequency connectors is greasy objects. During storage or use, if they come into contact with greasy objects, the connectors will also lose their original effectiveness and become an obstacle to our work.

RF connector RF coaxial connector Naming method of RF coaxial connector Model naming The model of RF coaxial connector consists of two parts: the main name code and the structure code, separated by a short horizontal line "-" in the middle. Main name code The main name code of the radio frequency connector adopts the internationally accepted main name code, and the naming of different structural forms of specific products is specified by detailed specifications. Structure form code Structure of radio frequency connector. (1) Selection of RF connectors 1. The selected RF connectors must conform to the actual frequency range. 2. Under normal circumstances, the electrical performance of straight RF connectors is better than that of curved RF connectors, and they can be selected according to actual usage. 3. The selected RF connector must have a smaller standing wave ratio. 4. The selected RF connector should have small insertion loss. 5. The selected RF connector should match the impedance of the mating RF connector or cable. 6. The EMC of threaded RF connectors is better than any bayonet or push-pull RF connectors. 7. When there are IM requirements, the material and coating of RF connector should be considered. 8. When the universal RF connector meets the requirements, the high-performance RF connector is not selected. (2) Selection precautions 1. Cost-performance ratio 2. Inventory and procurement cycle 3. Testability, reliability, easy replaceability, etc. 4. How high-frequency signals does the connector run. When customizing the pin distribution, consider signal integrity, pay attention to the distribution of signal and ground pins. 5. How much voltage and current the connector takes, consider power decoupling and thermal design bearing capacity, etc. 6. Contacts of the connector Number of heads. Under normal circumstances, follow the principle of fewer connectors and more contacts. 7. Installation method of the connector and precautions during installation. 8. Specific fastening method of the connector and whether there are any precautions. For example, whether it is necessary to ensure that there are no too high devices in a certain area around the connector to avoid device interference 9. Whether EMC issues need to be considered
