10.2.2 EMI
The TPSM5D1806E is compliant with EN55011 Class-B radiated emissions. Figure 10-3 and Figure 10-4 show typical examples of radiated emissions plots for the TPSM5D1806E. The graphs include the plots of the antenna in the horizontal and vertical positions.
EMI plots were measured using the standard TPSM5D1806EVM with ferrite beads (Murata, BLM18SG330SN1) in series with the input wires.
