ST25R3916 Power Transfer & Amplifier Design Assistance Needed

We are considering transferring power along with NFC communication using the ST25R3916 chip.

From one of the application notes, we found the following block diagram, as shown in the image below. According to the diagram, the power amplifier is placed in cascade with the matching circuit.

Could you please point us to relevant documents to help us design a power amplifier according to our requirements?

Hi,

I am not aware of this block diagram. From which AN did you get it?

It is possible to attach a power amplifier to ST25R3916 but we don't have documentation to share for this. One option for you could be to work your local ST sales team get support through this channel.

BR, Ulysses
