The mixer in the R820T is unknown. It is believed to be an image rejection mixer

for fine tuning the balance. So far nobody seems to have managed to make it 
appear to do anything.

Call up the Rafael people and get a non-disclosure signed, probably concurrent 
with an order for a million chips, for more information.

No need for that... the link posted by Andrea is very interesting :

Reading that forum reveals many things that otherwise it would have been possible only to find
after having signed a NDA...
