Hello everyone, I don't know where can I post my question, sorry if I post at wrong place.
My problem is what is the function of the component in red circle?
We have several AD9361 FMCOMMS3 board but some have "GU" type on the red circle like no.711921, some do not have that like no.654872.
Will this difference effect the behavior of AD9361 board?
Thanks a lot.
