so you are saying that folding noise will be higher at low frequency?
am I correct?

Little different.

If the mixer has such a strong effect on system noise figure,
why don't you increase LNA gain?
Click to expand...
It increases Intermodulation.

volker@muehlhaus said:
Why don't you show an example for your claimed effects?

Congratulations.
Show the effect on system performance in simulation, please.

Confirm by yourself with high ft transistor or loading capacitor at nodes as parasitics.
