The relationship between noise level and noise figure NF.
Technical Data: Low Noise Amplifier MAP301/302
■Low Noise Amplifier MAP301/302 Ideal for radiated noise measurement. For example, when passing through an amplifier with a 20dB gain, the input signal is amplified by 20dB at the output. This is understandable. But what happens to the noise? This is not well understood. In other words, while the signal is amplified by 20dB, if the noise is also amplified by 20dB, wouldn't the appearance of the signal remain the same? No, it is different. Let's consider the definition of NF (Noise Figure).
