RF connector interface structure selection need to refer to what factors

According to the relevant information sharing feedback shows that the RF coaxial connector in science and technology, military and ships and other fields have achieved high-frequency applications, it is used in the entire frequency range and a variety of assembly environments are consistent and stable. Its powerful application features prompted more and more people to explore in depthRF ConnectorFrequency power comparison table, now on the RF connector interface structure selection need to refer to what factors are briefly described:

1. Consider whether there is enough rotation space to connect the nut

According to scientific information analysis feedback shows that the RF coaxial connector must be matched with the nut to play a role, it has a threaded, bayonet and push-in and other types of different structural forms. Therefore, the user must consider whether there is enough rotation space to connect the nut when choosing to order, so as to avoid that the nut cannot be accurately connected due to too small space.

2. Consider the connection maintenance ability of the connector

The choice of the RF coaxial connector interface structure also needs to consider its connection maintenance capability. Because different interfaces have different connection service life, some interfaces have stronger resistance to damage during the impact and vibration periods, so their connection maintenance capabilities will be stronger; on the contrary, if some interfaces have less resistance to impact and damage, then their connection maintenance capabilities are also smaller.

3. Consider the characteristic impedance of the connector, operating frequency and voltage resistance and other parameters

According to the feedback shared by many manufacturers, the selection of RF coaxial connector interface also needs to consider the influence of parameters such as connector characteristic impedance, operating frequency and voltage resistance. For example, the matching ability of the connector to the transmission system and the cable impedance, whether the withstand voltage value of the coaxial connector meets the system withstand voltage requirements, and whether the operating frequency limit meets the environmental requirements.

RF coaxial connectors have been widely used in broadcasting satellites, radar, radio astronomy and other fields. The reason is that the design capability of RF connectors has been greatly improved. According to some sharing feedback, the selection of the interface structure of the RF connector needs to consider not only whether there is enough rotation space to connect the nut, but also the connection maintenance ability of the connector and the level of its electrical performance.
