Abstract
The present invention discloses a structure for suppressing electromagnetic radiation of a printed circuit board (PCB) with a network module, where the PCB is a multi-layer PCB comprising a first signal layer, a power layer, a grounding layer, and a second signal layer. The network module having an integrated circuit for controlling network functions and a network port is disposed on one of the side surfaces of the PCB and coupled with each circuit layer of the PCB. On the power layer, an area at the position of network port is divided and disposed as an analog ground (AGND) and a plurality of decoupling capacitors are connected between the AGND and the grounding layer of the PCB. The prevent invention can prevent the electromagnetic-coupled noise generated by the network module and the power layer from radiating outward in the way of electromagnetic radiation from the network port, so that the PCB can meet the requirements of the related electromagnetic interference (EMI) standards.
