The blocks Input signal parameter specifies whether the input is a power signal or a voltage signal, and the Convert to parameter controls the scaling of the output. dBm (or dBmW) and dBW are. Example: Convert 100 mW to dBm: P(dBm) = 10 · log10(100mW / 1mW) = 20 dBm. For example, 20 dBm = 100 mW or 40 dBV = 100 V. The formula bellow can be translated as: the power P(dBm) in dBm is equal to 10 times the base 10 logarithm of the power P(mW) in milliwatts (mW) divided by 1 milliwatt (mW):. 527 y = dbm (1+j*2, 25) returns 20. So 1 watt is equal to 30 dBm. So dB is a measure of power relative to 1 Watt and dBm is measure of power relative to 1 Milliwatt. 18 mW = rounding off to 500 mW Example 3:. The formula bellow can be translated as: the power P(dBm) in dBm is equal to 10 times the base. The following formula is used to calculate the power value (in W) for a given dBm value. If we have 1000 mW (or 30 dBm), that is the same as 1 W (or 0 dBW). If the antenna has a gain, this power gets concentrated in a particular direction. dBm-Volts-Watts Conversion - Qorvo dBm-Volts-Watts Conversion (50-Ohm System) Download PDF Disclaimer: Qorvo makes no representations or warranties of any kind, express or implied, about the completeness, accuracy, or reliability of the tools on this web page. How to convert watts to dBm The power P(dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P(W) in watts (W) divided by 1 watt (W): P(dBm) = 10 ⋅ log 10 ( 1000 ⋅ P(W) / 1W) = 10 ⋅ log 10 ( P(W) / 1W) + 30 so 1W = 30dBm Example Convert 20 watts to dBm: P(dBm) = 10 ⋅ log 10 (1000⋅20W) = 43.
