Hi,
I am required to make a 2 antenna design with a single NFC chip. I have tried the mfrc630 and an rf switch, with a single ended antenna design and by grounding the tx2 pin to accomplish this.
Upon further investigation I found out that the PN512 family has a TxControl register that allows to enable and disable each tx pin for controlling which antenna is transmitting and receiving. Is there any document on this approach and design? Also what chip would you recommend on using.
Thanks.
