Hi,
Has anyone ever used the mixer model in rflib, if yes is there a tutorial anywhere that explains how to use this block.
Also, there is an input called "plo" that is the LO power in the mixer model which is supposed to clip your LO signal if exceeds a certain level. However when I make the actual input LO power lower than "plo", changing the "plo" has an effect on my Noise Figure.
The Noise Figure measurements dont match the Noise Figure parameter that I input in the mixer.  
Thanks,  :)
