10.2.3 EMI

The TPSM265R1 is compliant with EN55011 radiated emissions. Figure 10-4, Figure 10-5, and Figure 10-6 show typical examples of radiated emission plots for the TPSM265R1. The graphs include the plots of the antenna in the horizontal and vertical positions.

EMI plots were measured using the standard TPSM265R1EVM with no input filter.
