Hi Gerhard, 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.

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.
