dBm to Watts Converstion Chart

 

dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). It is used in radio, microwave and fiber optic networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form.

It’s very important to check the P1dB to determine the Output Power

 Example 1:  Actox 6w Ku-Band BUC has a +38 dBm, according to the chart below, the Output Power is 6.3 Watts

 Example 2:  Advantech 40W Ku Band BUC has a +45 dBm, according to the chart below, the Output Power is 32 Watts.
