Original question:

Trf7970a's transmit power

Trf7970a & NFC power boost

Other Parts Discussed in Thread: TRF7970A

For the need of the project, I want to increase the communication distance of NFC(on the air) to more than 10 cm. The current configuration has a communication distance of less than 2cm.Reader IC is Trf7970A, tag IC is RF430L152H.

Now I try to increase the reading distance by inserting NFC power boost IC to increase transmit power.

Which chips can be recommend? Is there a corresponding reference design? Please Give me some advice.

Thank you!
