Look up 3rd order intercept point.

That's a helluva web site you keep there :-)
Impressive!

How high can the 74HC4066 as mixer go?
I need 50Mhz tops.

I still like to know how strong dual gate MOSFET is compared to say diode
ring.

thx

The HC4066 is OK(ish) to about 10megs.
A dual gate fet (eg 40673) -with care- should be able give out roughly the
same, or a little more voltage than what is coming in. With a diode ring
expect to pick up (say) only 40mV of an incoming 100mV.
[Easiest / most reliable]: use a "Bus Switch" such as the FST3125, toggled
by 74AC type logic; handle the A.C. signals by couple of video op-amps).
('Output' signal looks like what you see in a text book).
