Radio frequency connectors, also known as RF connectors, are usually separate components installed on cables or equipment for electrical connection of transmission line systems. It can be seen that it has the common feature of the "separate element" connector.
[RF coaxial connector]
The naming of RF coaxial connectors consists of two parts: the main name code and the structure code, separated by a short horizontal line "-". Main scale The main scale of the RF connector adopts the internationally accepted main scale. The naming of different structural forms of specific products is stipulated in the detailed specifications, and the structural form represents the structure of the RF connector.
RF connectors connect coaxial cables, microstrip lines or other RF transmission lines to realize the electrical connection, isolation or transfer of different types of transmission lines. They are mechatronic products and play the role of a bridge.
Classification and usage instructions of RF connectors.
RF connectors are mainly divided into three types: RF coaxial connectors, RF triaxial connectors and dual-core symmetrical RF connectors. Its main uses are:
1. RF coaxial connector: mainly used for the transmission of transverse electromagnetic waves (TEM waves);
2. RF triaxial connector: mainly used in transmission occasions that require high shielding performance, such as transverse electromagnetic wave (TEM wave) or pulse wave transmission;
3. Dual-core symmetrical RF connector: mainly used for digital signals with low transmission rates.
① The main performance parameters of RF coaxial connectors are: characteristic impedance, frequency of use, return loss, insertion loss, isolation, RF leakage, phase consistency, third-order intermodulation, etc.
②Common materials and coatings for RF coaxial connectors.
Mechanical Characteristics of RF Coaxial Connectors
The mechanical and electrical properties of RF connectors depend on the processing methods of various components in the manufacturing process. At the same time, the mechanical properties should also take into account the quantity and scale of production. Therefore, it is necessary to study the reasons why the specific performance cannot be satisfied, and such analysis will help to avoid the next error. The smaller the RF connector, the more difficult it is to process, the higher the processing cost, and the greater the processing accuracy and error. In the future, in industrial applications, there will be more demand for small, high-quality, and inexpensive electronic components.
