I suspect the paper you are referring to is:

Design Principles and Test Methods for Low Phase Noise RF and 
Microwave Sources (Scherer, 1978)

It is available on Didier's site at:


There are two other Scherer papers there:

Generation of Low Phase Noise Microwave Signals (Scherer, 1981)

The "Art" of Phase Noise Measurement (Scherer, 1985)
