How I perform the noise figure measurement if the output node of LNA is
high impedance node and not be matched to 50 ohms?
In my LNA design, I used LC tank to be the load, so the LC tank will be looked
as high impedance at operating frequency.
But, how to do the noise measurement, because the loading of NF meter will
degrade the gain of LNA.
Any one has experience on this?
