Hi everyone,
I am working with the X-NUCLEO-NFC08A1, which uses the ST25R3916B chip, and I am planning to use it's main IC (ST25R3916B ) with 6 antennas. The idea is to use the two RF interfaces of the chip, with each interface connected to 3 antennas.
I would like to know if anyone has experience or recommendations on how to handle antenna multiplexing for this setup. Specifically, I’m wondering whether it would be better to implement the multiplexing using PIN diode circuits or if it would be more suitable to use an RF switch. Are there any other solutions or approaches that should be considered? Do you have any specific IC (related) recommendations?
Additionally, I’d appreciate some insights on where the multiplexing circuitry should be located. Should it be positioned between the IC and the antenna circuit (IC-xx-AntennaCircuit-Antenna) or between the antenna circuit and the antennas themselves (IC-AntennaCircuit-xx-Antenna)?
Looking forward to your advice!
Best regards,
