A mobile system transmitting IF signals via a cable between PCBs (Printed Circuit Boards) can be vulnerable to electromagnetic interference (EMI), which may result from the connector itself as well as the interface between the connector and the cable. In this paper, the radiation physics of an RF cable and connector is comprehensively analyzed using a commercially available EM simulation tool. Several EMI mitigation solutions have been studied and a new ground island structure is proposed to reduce common mode current.
