dBm to Watts Conversion
It will be useful to know the equivalent dBm to watts power conversion when adding attenuation to the
modulator RF output.
Transmitters without amplifiers have a maximum RF output of 20dBm (100mW).
When calculating, do not convert the equivalent watt value until after the sum has been done:
i.e., 20dBm-3dBm = 17dBm (50mW)
