I found that in many papers, the IIP3 was simulated by a two-tone frequencies. But they didn't say how to select the two adjacent frequencies. While in my simulation, if i chose different frequencies, the IIP3 is different according. So what's the criterion?
In fact, i'm desinging a wide-band LNA(50~860MHz) now, the spec gives a IIP3 required. Should I satisfy the request in all the frequency range?
Also, could anyone give me some hints about how to improve the LNA' linearity?
Thanks.
