消除串扰自激的工程应用实例

The application of eliminate self-excitation crosstalk in engineering

在实际工程中,系统在设计加工出来以后,电路结构都已经确定,但是在调试过程中会出现各种问题,要求有大量调试的经验。文章以C波段的接收机的调试为例,给出了几种消除串扰自激的实例应用,从而很好的解决了射频高增益放大器由于串扰信号进入而引起自激的现象,使得系统工作状态正常稳定,为工程实践提出一些经验,借鉴。

In practical engineering, when system design and processing out, the circuit structure have been identified, but there will be a variety of problems in the debugging process, which requires that engineers have a lot of debugging experience. We take the debugging of the C-band receiver, for example, and proposed to eliminate the crosstalk of the self-excited instance of the application. A good solution to the RF high gain amplifier due to the entry of external crosstalk and the self-excited, in the end we making the system work normal and stable, some experience, and learn for engineering practice.
