Self-interference to IoT, cellular and wireless receivers from on-board energy sources, such as DC-DC converters, has become a real challenge for manufacturers. One possible mitigation is to absorb some of this radiated energy using ferrite absorber material, but manufacturers of this material usually don’t provide adequate absorption or shielding data. The presentation will describe a simple way to quickly characterize various materials to help determine the best one to use, based on receiver frequency. An interesting case study will also be described.
