One very common issue manufacturers face with wireless or IoT products is self-generated EMI from on-board DC-DC converters. These small circuits generally switch between 1 and 3 MHz and use very fast sub-nanosecond edge speeds. The result is broadband EMI often extending above 2 GHz. This EMI can affect the sensitivity of sensitive receiver circuits - especially cellular and GNSS. The presentation will describe a three-step process for characterizing self-generated EMI and offer tips on mitigation.
