linearity vs. feedback

[Puppet1]

hello i need information on linearity vs. feedback tradeoffs in mixer and LNA design and NOT power amplifier design.

thanks

i think in most simple way
the negative feedback will decrease the gain , as the gain decrease so the ouput power will not make the active devices saturate so the linearity will increase
