Thanks for the suggestions. I'll have a look at the web references.
Just a couple of notes on things that won't work.

Noise performance of Mar's MMIC's should be noted on datasheets.

Yes, but they never show the range of noise figures, only a typical or
worst case numbers. Of course if the noise figure is very low (PHEMT)
then the variability is pretty small as long as the circuit is done
right.

Terminate receiver with 50 Ohm resistor, measure output and label it
zero dB.

This doesn't work, because the noise is dominated by the receiver
noise, not the resistor thermal noise (unless the receiver is very
very good !).
