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.


Regards

Søren
