I am building solution on top of this design. I am planing to use ideal diodes with op-amp with much higher bandwidth than 30MHz and slew rate better than 145V/us.
I think this is the potential solution to remove voltage drop across the diodes and then amplify it.
What is interesting is I have the exact schematic from Beric Dunn's analyzer using the Si5351a chip.
When I use a the germanium diodes, I get a flat 1.0 reading across the bands with a 50 Ohm resistor load as expected.
When I try just replacing the germanium with Schottky (1N5711) I get an SWR of around 3 that slowly creeps up to 4.
I would really like to ...
