Noise matching is an adjustment (no power adjustment ) between an RF source Z i ( swelling resistance ) and a low noise amplifier (LNA), that is a low noise amplifier mainly for antenna signals with the minimum possible noise figure . This is i. A. not the same as optimizing the signal-to-noise ratio and thus the transmission or channel capacity .
