RF power ratio conversion compares output power against input power and expresses the ratio in decibels.
A positive dB value means output power is higher than input power. A negative dB value means output power is lower than input power.
Input Example
Power Output: 10 W Power Input: 1 W
Output
Power Ratio = 10 × log10(10 / 1) = 10 dB.
