RF Power Ratio Converter

This converter calculates the power ratio in decibels between the output and input power levels. It helps compare amplifier performance or signal losses in RF systems.

Formula

Ratio_dB = 10 × log₁₀(P_out / P_in)

Formula Explanation

• P_out is the output power in watts or milliwatts.
• P_in is the input power in watts or milliwatts.
• The logarithmic scale expresses the power gain or loss in decibels.

Example

Input: P_out = 200 mW, P_in = 100 mW

Result: Ratio ≈ 3.01 dB

Who uses it

Useful for RF engineers, technicians, and students analyzing power gains or losses in communication systems.
