Technique for lowering the noise figure in RF amplifiers [PDF]
, 1970 Low-level RF amplifiers are operated at noise figures at or near the theoretical minimum, while maintaining high-gain stability. Formulas for the minimum amplifier noise figure value are derived from the analytical noise-figure expression involving the ...
