ADM2867E Radiation

Hi,

I'm a DAFE in Japan. Our customer is interested in ADM2867E due to Low Radiated Emissions. Then he wants to know the data of Radiated Emissions higher than 1GHz. Could you please give us it?

Regards,

Hiroyuki

    Hi Hiroyuki, 

    The data was gathered between 1GHz and 4GHz in anechoic chamber 3m from a horizontal antenna, which is the worst case orientation.

    With peak detector the maximum emission from the evaluation board is 57dBuV/m @ 3.7GHz, 17dBuV/m margin to the EN55032 / CISPR Class B limit of 74dBuV/m.

    With average detector the maximum emission is 51dBuV/m @ 3.7GHz, 3dBuV/m from the Class B limit of 54dBuV/m.

    I am having difficulty sharing images on EZ at the moment, I will follow up with an image of the scan once the sharing issues are resolved. 

    Regards,

    Neil
