Analysis and Suppression Scheme of Based on the Interference Intermodulation Initiating Spurious Response

This paper analyzes three main disturbances manners which are "interference signal and the local oscillator signal generated by the combination of disturbance," the useful signal and interference signal generated by cross modulation interference "and" generated by the interference signal and interference signal intermodulation interference ". According to GJB 151B-2013[5] CS103, CS104 and CS105, these three conduction sensitivity requirements and test methods, the formulation lead to sensitive equipment (unacceptable) spurious response of EMI power limit, and can be used to suppress the spurious response of EMC index and optimization. Eventually it can reach the purpose of communication devices general EMC performance optimization.
