Hi,

We have a new projects that need to use NFC readers, and initially plan to use PN5180, the reading standard is ISO14443;

Now we needs to modify the differential output of the antenna part to a single-ended output, and use the RF switch to split the single-ended output signal into two channels, that is, according to the figure below, after matching the antenna to 50ohm, then divide the TX into TX1/TX2/ TX3/TX4, access to different antennas;

Hello,

Please accept my apologies but this has not been tested by us since all of our designs use both, TX1 and TX2 outputs and one antenna. Nevertheless, with a single-ended design only please consider that the output power will be reduced by 3dB (half).

Hope it helps!

BR,

Ivan.
