Since you have a NanoVNA, hook one up and try it.
Yep, that's the next on my list :)
talks about Switch Figure of Merit, with a note that SwFoM * 10 is the
highest frequency it will work at as a switch.
So, FoM = 1/(2*pi*Coff*Ron)
This is interesting value, will need to read a bit more, appears to represent N channel as RC comprised of Coff and Ron
It's not a circuit model, just an arbitrary number to allow comparing switches.
The linked articles talk more about the theory.
