dBuVdBuV is commonly used to specify receiver
sensitivity.
- 0.5 µV is equivalent to – 113
dBm
- 1.0 µV is equivalent to – 107
dBm
- 10 µV is equivalent to – 87
dBm
To convert from dBm simply subtract 107 from
the dBm value. (See Note-2)
Note:- dBm for
receiver sensitivity is based on a voltage level in µV, not a power
level in Watts. Mathematically, this is taken into account and does
make a difference to the decibel calculations.
- The
simple conversion from dBuV to dBm
only
applies for antenna systems with a impedance of 50 Ohm
