dBm to dBc Converter

dBm to dBc Converter calculator can be used to convert power level in dBm to relative power level in dBc (dB relative to carrier). This is useful in RF engineering for comparing signal power to a reference carrier frequency.

Input Parameters

Calculation Results

Calculation Formula

dBc = dBm - 10 * log10(f_carrier / f_reference)

Where:
dBc = Power level in dB relative to carrier
dBm = Input power level in dBm
f_carrier = Carrier frequency in Hz
f_reference = Reference frequency in Hz

Result

Output Power (dBc): --

Learn how to use the dBm to dBc Converter calculator and its working principles

How to Use This Calculator

  1. Enter the carrier frequency in MHz (the frequency you're measuring relative to)
  2. Enter the reference frequency in MHz (the frequency you're comparing against)
  3. Enter the input power in dBm (the power level you want to convert)
  4. Click the "Calculate" button to compute the power level in dBc

Understanding dBc

Practical Applications

This calculator is particularly useful in:

  • RF and microwave engineering for comparing signal power levels
  • Telecommunications for measuring adjacent channel power
  • Test and measurement applications where relative power levels are important

Example

Suppose you have a carrier frequency of 2.4 GHz (2400 MHz), a reference frequency of 2.38 GHz (2380 MHz), and you measure an input power of -30 dBm. The dBc value would tell you how much lower in power the 2.38 GHz signal is compared to the 2.4 GHz carrier.
