The Importance Of The Connection Between The SMA Microwave Connectors And PCB
 Oct 17, 2019|View:5

Because nowadays, the requirements of SMA microwave connectors developing a board to the middle connection of the board are more and more big. The vertical distance between the top, bottom, left and right parallel plane circuit boards of SMA microwave connectors can not be ensured to be the same, and there is parallel plane displacement on the alignment between the two boards, especially when there are multiple channels in the middle of the two boards connected together. Because it is the transmission of RF data signal, an excellent overall connection for RF characteristics seems to be very important.

The Importance Of The Connection Between The SMA Microwave Connector And PCB

These characteristics include small data signal characteristics and large data signal output power characteristics. Otherwise, the characteristic impedance is not matched, resulting in a large attenuation coefficient of the reflection surface of the data signal, a small transmission data signal, and a poor output power bearing capacity. The sma-max board has great radial and axial capacity and output power bearing capacity for the board connector components, which is suitable for the application of several RF channels on the board that need to be connected together. Sma-max board to board connector is a fluctuating structure, which is composed of a snap seat welded with PCB, a sliding seat welded with PCB and its adapter bullet in the middle. The two bases are welded on two printed circuit boards respectively, and three patch RF connectors and two printed circuit boards form the connector circuit board assembly.


Different scenes are used for different PCBs, and the RF characteristics of the SMA microwave connectors connected to different PCBs are quite different because the transmission power circuit is not matched. It can be adapted not only by changing the layout of the PCB. Therefore, the connector and PCB layout should be designed according to the user requirements to ensure good RF performance with different tolerances.


Because the RF connector used in the communication industry board and board interface is not the same, the customer's circuit board is not the same. Therefore, it is very necessary for the design concept of technical specialty to use the place. Since 2007, the Teruilai department has been developing, designing and manufacturing new products for the market demand of the RF communication industry. We are very grateful to our old customers for their support and trust!
