Electromagnetic compatibility (EMC) design is essential for power  splitters to ensure that they do not interfere with other electronic devices and  are also immune to external electromagnetic interference. One of the key aspects  of EMC design in power splitters is shielding. The power splitter can be  enclosed in a metallic shield. The shield acts as a barrier to prevent  electromagnetic fields from radiating out of the power splitter and also  protects it from external electromagnetic fields. The material and thickness of  the shield are carefully selected. For example, a thick aluminum shield can  provide effective shielding against both electric and magnetic  fields.

Another important technique is filtering. Filters can be  incorporated into the power splitter's circuitry to suppress unwanted  electromagnetic signals. Low - pass filters can be used to block high -  frequency noise, while high - pass filters can be employed to remove low -  frequency interference. The design of these filters is based on the frequency  range of the power splitter's operation and the types of interference it is  likely to encounter.

In addition, grounding is crucial for EMC. The power splitter  should be properly grounded to provide a path for the dissipation of any induced  electrical charges. A good grounding system helps in reducing the potential for  electromagnetic interference. The grounding connection should be low -  resistance to ensure efficient charge transfer.

Furthermore, the layout of the components within the power splitter  also affects its EMC performance. Components should be arranged in a way that  minimizes the coupling of electromagnetic fields between them. For example,  sensitive components should be placed away from sources of strong  electromagnetic radiation. By implementing these EMC design techniques, power  splitters can operate effectively in a complex electromagnetic environment  without causing or being affected by interference.
