SUPPRESSING METHOD OF ELECTROMAGNETIC INTERFERENCE FOR MULTI-SPECTRUM SIGNALS

Abstract

With the rapid development of science and technology, electronic systems are becoming more and more complex and miniaturized. In a narrow space, there are multiple control signals. Aim at interference suppressing problem of multi-spectrum signals, the characteristics of intermodulation and crossmodulation interference has been studied, working frequency and bandwidth of multi-spectrum signals system are optimally designed for frequency controlling. A high-isolation multi-channel signal selection circulator network is proposed. The comprehensive method of filtering and isolation is used to solve the problem of channel mutual interference.
