My last message was meant in response to Oristo. Forgot to quote it.
"Use of 74LVC4066 Quad bilateral switch instead of SA612 mixer is elegant;
given square wave Si5351 output, its ideal mixer becomes a switch...
That would be a nice upgrade for nanoVNA2 (picoVNA?)"
It might also be better to redesign the resistance bridge for wider impedance measurement.
Current balanced 50 ohm bridge, NanoVNA design, does not have wide range. The FA-VA5 and EU-1KY antenna analyzers
have different front end designs. The FA-VA5 has a reasonable measurement range of 5 to 1000 ohms, far better than NanoVNA.
