The amount of power that can be consumed from the field depends on several factors, such as the field strength itself, the coupling coefficient between the Reader and Target antennas and the form factor of the antennas as well as the corresponding matching/tuning circuits. So because of these variants I would like to understand your question better.</P><P></P><P>Regards!</P><P>Jorge Gonzalez</P></BODY></HTML> Sat, 08 Apr 2017 01:06:18 GMT https://community.nxp.com/t5/NFC/How-much-power-allowed-to-be-consumed-by-the-NFC-Rx/m-p/646207#M1646 Jorge_Gonzalez 2017-04-08T01:06:18Z
