Hi, August,
Thanks for replying. I agree with all of your points.
However, here comes another question, admitted that the phase noise integration should have a lower limit, then what value should it be? 100Hz? 1K? or 10K?
As we all know, transceivers in all application have some accumulated phase error system spec, i.e., 2 degree or less for 11g maximum rate. Among all the phase error contributors, LO and mixer are the two biggest one. So we must have a definate method and spec for measuring LO integrated phase error. Stating integrated phase noise without stating the lower limit is simply not a fair comparison. Integrating from 1K will have definately better numbers than integrating from 100Hz.
Then, is there any industial standard for the lower limit to integrate phase noise?
