Phenomenon 1 during RF debugging

In the process of RF debugging, it is found that it is very different from the expectations at the time of design, and various unexpected problems will occur, especially some problems are not caused by design, such as the virtual welding of a certain device.If the signal is intermittent, the way to eliminate it is to test in sections. There are similar situations such as the connector seems to be broken and the connector is worn internally. For this kind of failure phenomenon caused by non-design reasons, the solution mainly depends on experience., knowledgeable is the basis for quick problem solving.For circuits with sensitive distribution parameters, the grounding of the device must be paid attention to. The signal reference ground cannot be disconnected on the path of the RF signal, so as to avoid the failure of various influence indicators caused by signal reflection, although these phenomena will increase the debuggingresistance, but more is the experience gained from this, combined with the law of theoretical formation, is the necessary process to finally achieve mass production!for reference only!
