The calculator converts from radiated power in dBuV/m (deciBel microvolt-per-meter) at 3 meters to conducted power in dBm at the output of the transmitter.
Example Calculation
In this example we compute the maximum transmitter power in dBm from the level of the radiated field 3 meters away.
For frequencies above 960 MHz, the FCC stipulates a maximum radiation limit of 500 uV/m at 3 meter distance from the transmitter. Use this calculator to convert uV to dBuV.
500 uV/m equates to 54 dBuV/m.
A field strength value of 54 dBuV/m equates to a power level of -41.2 dBm at the transmitter.
Output Power of Wholehouse FM Transmitter
I was trying to figure out the output transmit power of the Whole House FM transmitter.
The FCC report shows a maximum average level of 41.42 dBuV in the FM band. This translates to -53.78 dBm at the output of the FM transmitter.
