dbm to watts conversion for radio, radar and microwaves Decibels are used to represent the ratio of two quantities of power: db = 10 log P1/P0 . In the case of dbm the reference power P0 is 1 milliwatt : dbm = 10 log P1/1mw. Inverting this equation gives the power in terms of the...

For the common unit of dbm the equation is P1= 1mw·10dbm/10. Why? It is not unusual in a radio, radar, or microwave system to have 100,000 watts of transmit power, 1 microwatt of receive power, and various gains and losses from antennas, distance, and absorbing media. Adding and...
when all receiving antenna gains and transmission line losses are not identical for all receivers. To determine the level of field strength necessary to adequately receive a transmitted signal, use Equation 6 above, taking into account the frequency, receiving antenna gain and required leve...
VREF is the full-scale reference voltage of the ADC, in volts. LSB is the smallest quantized voltage that the ADC can resolve, in V/step or V/bit. Solve for VOUT using VOUT = CODE × LSB Substituting this expression in the previous VIN equation yields VIN CODE LSB INT...
electromagnetic force, or EMF. The force of air pressing against the resistance of the eardrum or microphone diaphragm, is analogous to the force of a battery pushing electrons against the resistance of a circuit. Therefore, just like dBvolts, the sound pressure level ratio equation is the ...
I can then use the power equation to determine the source voltage. It's extra work and a good mental exercise, but ultimately I still get the output voltage. If the output level is given in dBm without a specified source impedance, the rating is useless. Why? Because there is no way ...
