WebΔF = Noise Bandwidth (Hz). At room temperature (290ΔK), the noise power density P NAD = -174dBm/Hz. Thus we have the following equation: NF = P NOUT - (-174dBm/Hz + 10 * log 10 (BW) + Gain) In the equation, P NOUT is the measured total output noise power. -174dBm/Hz is the noise density of 290°K ambient noise.
