mW to dBm Conversion dBm Definition: dBm is the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). 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...
10000000000 mW 100 dBm mW to dBm Conversion dBm Definition: dBm is the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). 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(...
The formula for calculating dBw is: Conversion of dBw and dBm: 0 dBw = 10log1 W = 10log1000 mw = 30 dBm P =dBW Power :P =dBm p =W Enter the corresponding value and click "convert" to convert the calculation.
dBm is referenced to one milliwatt (0.001 W). dBW value in dBm is always 30 more because 1 watt is 1000 milliwatts, and ratio of 1000 (in power) is 30 dB, eg 10 dBm (10mW) is equal to -20 dBW (0.01 W). Input a value above, select the type of unit you wish to convert, ...
EIRP and Antenna Gain The following formula can be used to calculate the EIRP limit related RF power based on selected antennas (antenna gain) and feeder (Coaxial Cable loss): EIRP = Tx RF Power (dBm)+GA (dB) - FL (dB) The following table describes this formula: Table 5: Formula ...
