For a sine wave into a 50 Ω load, the following table relates dBm to voltage.
For 75 Ω or 600 Ω loads, use the following conversions.
dBm (75
Ω ) = dBm (50 Ω ) – 1.76
dBm (600
Ω ) = dBm (50 Ω ) – 10.79
dBm RMS Voltage Peak-to-Peak Voltage
+23.98 dBm 3.54 Vrms 10.00 Vpp
+13.01 dBm 1.00 Vrms 2.828 Vpp
+10.00 dBm 707 mVrms 2.000 Vpp
+6.99 dBm 500 mVrms 1.414 Vpp
0.00 dBm 224 mVrms 632 mVpp
-6.99 dBm 100 mVrms 283 mVpp
-10.00 dBm 70.7 mVrms 200 mVpp
-36.02 dBm 3.54 mVrms 10.0 mVpp
