SAW FiltersEMI (electromagnetic interference) optimization is a crucial aspect of saw filter design. SAW filters are a type of electronic filter that uses surface acoustic waves (SAW) to filter out unwanted frequency signals. EMI optimization involves designing the filter to minimize the amount of EMI that is generated or transmitted by the filter. This is often achieved by carefully selecting the materials used in the filter and by using shielding and other techniques to reduce the amount of EMI that is emitted. Additionally, proper placement of the filter within the electronic device can also help to reduce EMI.
