RF coaxial connector, or RF connector, is a small electronic component installed on a cable or instrument. Its main function is to act as a bridge in the process of electrical connection or separation.
Discussion on the development trend of RF coaxial connector
As far as the current development situation is concerned, RF coaxial connectors mainly have the following main development directions: miniaturization, high frequency, low electromagnetic loss and leakage, and high power.
1. Miniaturization
The miniaturization of the whole system has gradually reduced the size of the RF coaxial connector, and the main representative is the SMP series RF coaxial connector.
The miniaturized product of the SMP series is the SMPM series RF coaxial connector. This connector has the characteristics of small size and light weight, and its volume is only 70% of the general SMP series.
And the maximum operating frequency can reach 65 GHz, which has been widely used in military and civilian fields.
SMP and SMPM series connectors are attracting more attention in more fields
In the civilian field, microwave communications and high-precision measurement have a high demand for micro connectors
In the military field, due to its high installation density and high frequency of use, SMPM series connectors have gradually been used
And in the highly concerned 5G technology field, SMPM connectors also have very good application prospects.
2. Low electromagnetic leakage
The leakage of electromagnetic waves is an inevitable phenomenon when electronic equipment is running.
These electromagnetic waves contain certain working information, and if these electromagnetic waves can be captured with the help of capture equipment, information leakage will be caused, which poses a great threat to technology and production safety
In addition, electromagnetic leakage will also have a negative impact on the internal electrical components of electronic equipment. Therefore, electromagnetic leakage during equipment operation must be reduced as much as possible, and RF coaxial connectors are the key components for shielding electromagnetic waves.
3. High power
The power of the connector is related to both the hardware structure of the connector, such as size, and external factors such as the operating environment and frequency of use of the connector.
In the development process of RF coaxial connectors, it is important to establish the power mathematical model of the connector. The power mathematical model of the connector is related to the type of connector, and is also directly related to the operating temperature and operating pressure of the connector.
When establishing it, it is necessary to fully consider various factors and not be limited by the model factor.
At the same time, multiple derating curves such as power-temperature and power-connector electrical performance are established.
4. Diversification of functions
Signal processing will become the main function of RF coaxial connectors. Signal processing functions include filtering, phase modulation, mixing, attenuation, detection, limiting, etc., which will be widely used in the future.
