10.5 EMI

The TPSM53603 is compliant with EN55011 Class-B radiated emissions. Figure 10-5 and Figure 10-6 show typical examples of radiated emissions plots for the TPSM53603. The graphs include the plots of the antenna in the horizontal and vertical positions.

EMI plots were measured using the standard TPSM53603EVM with no input filter.
