As for your AD-FMCOMMS1-EBZ,
do you have a good idea that send the signal to VGA/AD8366 without demodulation by ADL5380 on Rx directly?
I confirmed your schematic for find this solution. But there is no way maybe.....
The to use a balun to do single ended to diff if you want to bypass the RF (which also bypasses the VGA).
If you like to hack up the board, what you can do is run traces from the output of the balun to the input of the VGA (L32, 34, 28, 26). simply remove these inductors and connect them to the side of JP1 and JP3 that is tied to T11.
Make sure you set the common mode voltage appropriately as well. (R76 and R116)
It's not going to look 100% but it's one way.
Thanks for your quick reply!!
That's a good idea.
We will try it.
