dBuV

dBuV is commonly used to specify receiver sensitivity.
  • 0.5 V is equivalent to 113 dBm
  • 1.0 V is equivalent to 107 dBm
  • 10 V is equivalent to 87 dBm
To convert from dBm simply subtract 107 from the dBm value. (See Note-2)

Note:
  1. dBm for receiver sensitivity is based on a voltage level in V, not a power level in Watts. Mathematically, this is taken into account and does make a difference to the decibel calculations.
  2. The simple conversion from dBuV to dBm only applies for antenna systems with a impedance of 50 Ohm !
