[Moon] all you need and more....

[graham]

I am indebted to Dick K6HIJ for posting this link on the U.S. Microwave 
reflector.....

the last item (book) on this page covers LNAs and all associated subjects.

I have only had a short time to skim it....

No matter what you really know about Noise and LNAs , or think you know, 
this document will be invaluable to you, it should be mandatory reading for 
anyone into EME. It contains every formula and every measurement/analysis 
you are ever going to need, all in one PDF.

Some of it is heavy going, some of it could not be easily/practically 
applied in 'amateur' systems but ALL of it is compulsive reading. Even if 
just to go 'oooh' and 'ahhhh' at some of the pictures and concepts.........
