If you look at application notes, the noise figure varies with
source Z. It is most quiet between 200 and 700 ohms. Much lower
or higher, it gets noisy. Also, it has a lot of gain right up
into VHF range. It will oscillate if not properly decoupled or
if ouput loading is to high. These spur oscillations will sound
like noise. The product of Rs X Rl should be less than 3500000.
