In practice, Microwave components and devices often provide some attenuation. The amount of attenuation offered can be measured in two ways. They are − Power ratio method and RF substitution method.
Attenuation is the ratio of input power to the output power and is normally expressed in decibels.
Attenuation in dBs=10 log(P_in/P_out )
Where, P_in=Input Power & P_out=Output Power
