Hello to everyone!
I have designed an double balanced mixer in Ka band. When I count an mixer's IIP3 in downconvertion mode, I have a result about 16-18 dBm in my band. But... When I do the same count, but in upconvertion mode, I have a lower value IIP3, about 11-12 dBm. :-|
I found the same situation in Avago AMMP-6545, but I don't understaind it... Could some one tell me a physical cause for lowering IIP3 in upconvertion mode? Or, may be, could some one tell me the name of a book, or a paper, where I could find a reason for my problem?
Thanks a lot
