The RFID controller such as PN7150B0HN/C11002Y or the general MRF522 reader with the match network the impedance is about 37-ohm, whether can I use a balun to transfer to impedance to 50/75-ohm single-ended signal for coaxial transferring?
There is a picture in the doc AN11314 Multiple Antennas on Single Reader IC.
The TX2 pin is not used, whether it would affect the access distance?
The document I am getting now, so far is not in hand.
Could you help to check my idea?
Hi Ernst,
I will send the related diagram on the usage of single-ended antenna by personal email. check it , please!
Have a nice day!

Hi Wigros,
our customer also want to MFRC6xx single ended antenna design for cost reduction.
if possible, please also share related design doc?
thanks,
