RF Power Ratio Conversion Calculator

This calculator converts the power ratio between output and input power into decibels (dB). It is commonly used to express amplifier gain or attenuation in RF systems.

Formula

Ratio_dB = 10 × log₁₀(P_out / P_in)

Parameters

• P_out = Output power (in Watts or milliwatts)
• P_in = Input power (in Watts or milliwatts)
• Ratio_dB = Power ratio in decibels (dB)

Example Calculation

Input: P_out = 100 mW, P_in = 10 mW

Calculation: Ratio_dB = 10 × log₁₀(100 / 10) = 10 dB

Result: Power ratio = 10 dB
