Hello, I am trying to understand the IIP3 concept a bit better. I get the general idea that it is a non-linearity measure of mixer that takes one tone, applies a non linearity and it will interfere with another one of different frequency. According to this graph http://en.wikipedia.org/wiki/Image:Interceptpoint.png am I supposed to look for a large positive dBm to get good performance?
Looking at the below figures: AS8347: +11.5dBm softrock40: above 30dBm would this mean that the H mode FET switch mixers are far superior to analog mixers in the IIP3 spec? Also, if I look at PA3AKE's comparison http://www.xs4all.nl/~martein/pa3ake/hmode/ How am I supposed to interpret a table like: http://www.xs4all.nl/~martein/pa3ake/hmode/fsa3157.html Thanks, Frank
