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

	Stage 1	Stage 2	Stage 3	Total
Gain (dB)				3.00
NF (dB)				0.00
P1dB (dBm)				100.00


Total Gain (dB) = Gain₁ + Gain₂ + Gain₃
*Total NF (dB) = 10log10(nf₁ + (nf₂-1)/gain₁ + (nf₃-1)/(gain₁gain₂)*
*Total P1dB (dB) = 10log10((1/(p1dB₁gain₂gain₃) + 1/(p1dB₂gain₃) + 1/(p1dB₃))^-1)*

Note: The calculations for Total P1dB and NF use linear values (NOT dB) for nf, p1dB, and gain.
