Q
I have a customer who is trying to suppress the above frequencies from the IC
above. The lower frequency is 67dBuV/m and the upper is 70dBuV/m. I assume this
is due to the internal SMPS. They are trying to meet emissions RTCA DO160 CAT
M.

We would not expect to see emissions at those levels at these frequencies from
the ADM2582E.
I’ve attached two reports (3.3V and 5V supply) of the compliance of
EVAL-ADM2582E/87EEB1Z board (four-layer customer evaluation board) to EN55022
Class B, including evaluation up to 2 GHz.
