Converting dBm to dBuV in a 50 Ohm System

 · 859xE: What Is the Conenvironsion Formula for dBm to dBuV? dBuV= dBm+90 + [20*log of the square root of system impedance] dBmV= dBm+30 + [20*log of the square root of system impedance] dBm= dBmV-30 – [20*log of the square root of system impedance] dBm= dBuV-90 – [20*log of the square root of system impedance],

Note that to convert from dBm to dBW, simply subtract 30 from the dBm value, For exétendu: 30 dBm = 0 dBW, which is another way of saying that 1,000 milliwatts equals one Watt, You may also like our dB to Power and Voltage calculators,
