We have designed a device with XB3-24Z8UM-J module for wireless communication. Testing the device in laboratory to certificate it we have discovered that it failed in radiated immunity (10V/m field).
Analyzing the problem in depth we have discover that the problems are in frequencies between 80 and 84MHz and they get the PCB through the XB3 antenna cable.
My doubt is if it should be possible to install a low frecuency ferrite en this antenna cable without affecting the range of the wireless communication.
What do you think?
