Cascade Calculator

    Enter gain, noise figure, and P1dB to calculate cascaded system performance.

    Stage 1 Stage 2 Stage 3 Total

    Gain (dB)

    NF (dB)

    P1dB (dBm)
    • Total Gain (dB) = Gain1 + Gain2 + Gain2
    • Total NF (dB) = 10*log10(nf1 + (nf2-1)/gain1) + (nf3-1)/(gain1*gain2)
    • Total P1(dB) = 10*log10((1/P1dB1*gain2*gain3) + 1/(P1dB2*gain3) + 1/(P1dB3))^-1)
    • Note: The calculations for Total P1dB and NF use linear values
