CLRC663 Multi-antenna polling work with what switch IC appropriate, external PCB antenna matching need to pay attention to what? Thank
Hello JiWei,
if you want to use multilple antenna, you can use 50-OHM single-end antenna. the solution like this:
---PN532---Antenna Switch( <100MHz, and suitable for 13.56MHz, 50OHM)------->Multiple Single-end antenna.
and you can use HOST(MCU or procoessor) to control how to switch channel.
In addition, you can also use MOSFET to be switch.
Have a nice day!
