While I respect your not wanting to spend time on the drawings...without them the value of your work is interesting but nearly useless to most of the rest us.
Things that will help the rest of us LEARN from your endeavors
1) A simple hand sketch (perhaps you keep an engineering notebook?). It doesn't appear that it is that complicated on the surface from the one picture of the board ...but who knows?
2) A short dialogue about the changes you have made along the way and why? So we are not doomed to retrace the dead ends you have already been down, if we are forced to reinvent your endeavors
I myself own one of the series units which for the moment is working hopefully I will never have to go down this road ..but if I? ( and others) do have a failure it would be nice if we did not have to reinvent the wheel so to speak. If your longer term goal is to produce these for a profit Then that is an all together different matter and I respect that.? I do not get the impression? from your notes to this point that is the goal here ...but??
Sorry If I have wasted your time
Regards & 73

I have tried yet another version and confirmed that it now covers 4GHz and and 3GHz instruments.
Component changes are part of live design process, Dave, - everything needs to fit onto 6x8mm PCB.
What's your plan with the schematic?? I don't want to waste my time on drawings. If you are planning on making a PCB I'd rather wait and buy one off you instead of wasting time with this.? My end goal is to continue my phase noise measurement experiments that were halted due to E4435B and E4425B failures.
Ideally, I would have bought guaranteed working 1GC1-4210 online but all the offerings are dodgy - even the pictures of "new" ICs show bent pins.? It would cost ?100 and few weeks to gamble and find out the result.? And at the end of the day, 1GC1-4210 seems to be fundamentally flawed so putting a new one in is planting a new ticking bomb.
Thanks
