In the process of high-frequency microwave circuit board design, if possible risks can be predicted in advance and avoided in advance, the success rate of high-frequency microwave circuit board design will be greatly improved. When evaluating projects, many companies will have an indicator of the success rate of one-board design of high-frequency microwave circuit boards.

　　The key to improving the success rate of a board lies in the signal integrity design. There are many product solutions for current electronic system design, and chip manufacturers have already completed them, including what chips to use, how to build peripheral circuits, and so on. In many cases, hardware engineers hardly need to consider the circuit principle, but only need to make the high-frequency microwave circuit board by themselves.

　　 But it is in the process of high-frequency microwave circuit board design that many companies have encountered problems, either the high-frequency microwave circuit board design is unstable or does not work. For large enterprises, many chip manufacturers will provide technical support to guide the design of high-frequency microwave circuit boards. However, it is difficult for some SMEs to get support in this regard. Therefore, I tried to find a way to complete it by myself, so many problems occurred, and it may take several editions and a long time to debug. In fact, if you understand the design method of the system, these can be completely avoided.

　　 Next, let’s talk about three techniques to reduce the risk of high-frequency microwave circuit board design:

The signal integrity problem is considered in the system planning stage. The whole system is built in this way. Can the signal be received correctly from one high-frequency microwave circuit board to another? This needs to be evaluated in the early stage, and the evaluation of this problem is actually not It is not very difficult. If you understand a little signal integrity knowledge, you can do it with a little simple software operation.

　　 In the process of designing high-frequency microwave circuit boards, use simulation software to evaluate specific wiring and observe whether the signal quality can meet the requirements. The simulation process itself is very simple. The key is to understand the principle of signal integrity and use it for guidance.

　　 In the process of making high-frequency microwave circuit boards, risk control must be carried out. There are many problems that the simulation software has not yet solved, which is controlled by the *** designer. The key to this step is to understand where there are risks and how to avoid them. What is needed is knowledge of signal integrity.

　　 If these three points can be grasped in the design process of high frequency microwave circuit board, then the risk of high frequency microwave circuit board design will be greatly reduced, the probability of error after the board is printed will be much smaller, and the debugging will be relatively easy.
