Enter gain, noise figure, and P1dB to calculate cascaded system performance.
Total Gain (dB) = Gain1 + Gain2 + Gain3
Total NF (dB) = 10*log10(nf1 + (nf2-1)/gain1) + (nf3-1)/(gain1*gain2)
Total P1dB (dB) = 10*log10((1/(p1dB1*gain2*gain3) + 1/(p1dB2*gain3) + 1/(p1dB3))^-1)
Note: The calculations for Total P1dB and NF use linear values (NOT dB) for nf,
p1dB, and gain.
