[Moon-net] Preamp measurements during conference

[Paul Chominski]

Hi All,
I am not sure if this is not too late, but I would like to suggest measurement of linearity along with NF measurements.
I will be happy to help performing those measurements, but unfortunately I can not take instruments with me.
We might measure P_1dB compression point or two-tome IM3 and calculate IP3.
For P_1dB compression we need only Network Analyzer with wide range of power or signal generator and spectrum analyzer. For two-tone IM we will need two signal generator, power combiner with good isolation ( three attenuators will help) and spectrum analyzer.

I think it will be helpful to correlate NF, Linearity and performance of the LNA's. This might help us to understand what is important in today's noisy radio environment.
