Hello,
Is there a way to connect the remote antenna to the NFC chip (e.g. PTX105R) via a coaxial cable? There is no space for the NFC chip where the antenna is to be mounted and we only have the option of using a coaxial cable for the connection.
Since it is essentially a matter of adapting the balanced circuit of the NFC chip to the unbalanced coaxial cable, shouldn't a balun like this one DXW21BN2511N actually be used?
