As a first indication, when calculate parameters of mixer linearity, have to use the same definitions as for LNA. LO signal is considered as part of the mixer, and not as an input signal.

Hi Vfone

Hi vfone,

Thanks for the links. Especially the third (Anritsu) and the fifth (Aeroflex/IFR) are very useful and give a deeper insight and practical aspects too.
