They produce as low as noise possible especially when we have very low amplitude in input terminals (uV, mV).

It's typical for the first stage after the antenna for RF systems. It is important to use a LNA (typ. A~10) in order to minimize additional SNR loos caused by the amp. Amplifier stages afterwards will boost (amplify) the signal to the value needed.
