Wow - what a nice piece of work. If you or anyone in our group is going to make boards or completed units I would be interested in two of them. I do not have the expertise to build them.

So is any of the rest of the family still speaking to you? :) That’s a lot of work. Very nicely done and documented !!
Phase noise or ADEV would be well worth checking out. I see no reason why they would be a problem, but one never knows until the test is run.
I would suggest *some* resistance to ground on the outputs of the distribution amp. Without any R, you can get into ESD issues when you connect a cable. Is it a big deal - not really.
