    Dear Stefan

    I have been in contact NXP support regarding this issue.
    They have pointed out that the protocol settings should be loaded prior to setting the cw-amplitude and the field should be on.

    I can detect a small change in amplitude measured after the EMC filer on TX1 but the over all power consumption does not change enough for us to get below 100mA for the complete product so we will have to change the impedance matching circuit for the antenna.

    Hi Team

    Thank You for your reply - I'll take another look at our antenna matching as that could limited the power delivery to the transponder.

    One other question : Does the DESFire EV2 chip require more power to work than the EV1 ?


    Regards
