It uses a simple formula and programmed controls to execute the conversions. $\begingroup$ So my problem with your edited question is still: if you use physical units (dBm), amplitude square is still not a power, as discussed in my other comment. You're missing the units of your power-to-amplitude-square relation, and since that defines the answer to the question "should I be using dBm or dBW" (you probably should not use either, judging by the struggle you're having isolation (db) lo=+10dbm lo=+13dbm lo=+16dbm mac-60mh+ l-r isolation 10 15 20 25 30 35 40 45 50 55 60 1630 2180 2730 3280 3830 4380 4930 5480 6030 frequency (mhz) isolation (db) lo=+10dbm lo=+13dbm lo=+16dbm mac-60mh+ rf vswr 1.0 2.0 3.0 4.0 5.0 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 frequency (mhz) vswr lo=+10dbm lo=+13dbm lo=+16dbm CONVERSION CHART dBm <=> Watts <=> Vrms <=> V pp Note: The power to voltage conversions shown are valid only for Sine Waves and 50 Ohm Load Impedance. dBi = dB(isotropic): The forward gain of an antenna, measured in decibels (dBi), The dBi value reflects the antenna's directional / beamwidth characteristics, i.e., directional as opposed to omnidirectional: Generally, the higher the gain (dBi), the narrower the beamwidth - the more directional the antenna. dB relative to 1mV RMS.

How to convert dB to dBm; dBm to Watt, mW, dBW conversion table; dBm definition. dBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW). The power in decibel-milliwatts (P (dBm)) is equal to 10 times base 10 logarithm of the power in milliwatts (P (mW)): P (dBm) = 10 ⋅ log 10 ( P (mW) / 1mW) The index u at decibel (dB) means unloaded source, V (volt).Some say: The "u" in dBu implies also that the load impedance is unspecified, or unterminated and is likely to be high. The index m at dB (decibel) means 1 milliwatt (power) as reference value for 0 dB. If the reverse conversion dBu, or dBV to volts is needed, go to the converter at the bottom.

You see, 10dBm = 10^(10dBm/10) = 10mW, 20dBm = 100mW and 20mW = 10log(20mW) dBm = 13dBm. dBHz or dB-Hz or dB(Hz) (decibel hertz, amplitude ratio) — absolute unit for measuring bandwidth in decibels relative to 1 Hz. For example, 20 dB-Hz corresponds to a bandwidth of 100 Hz and 60 dB-Hz corresponds to 1 MHz. This unit is commonly used in link budget calculations. Se hela listan på analog.com So for dBm = 10*log (V*V/50/0.001) = 10*log (V*V/0.05) where V in RMS. Vrms = 0.707 Vp = 0.707*Vpp/2 To go the other way, V*V/.05 = 10^ (dBm/10) and solve for V where “ ^ ” means to the power.

dBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW). The power in decibel-milliwatts (P (dBm)) is equal to 10 times base 10 logarithm of the power in milliwatts (P (mW)): P (dBm) = 10 ⋅ log 10 ( P (mW) / 1mW) The index u at decibel (dB) means unloaded source, V (volt).Some say: The "u" in dBu implies also that the load impedance is unspecified, or unterminated and is likely to be high. The index m at dB (decibel) means 1 milliwatt (power) as reference value for 0 dB. If the reverse conversion dBu, or dBV to volts is needed, go to the converter at the bottom. Convert 13dBm to milliwatts: P (mW) = 1mW ⋅ 10 (13dBm/ 10) = 19.95mW. dBm to mW conversion table dBm Converter.

RF Engineers often express the power in dBm. The formula gives voltage value corresponding to a power value in dBm and Vice Versa. Following is the formula for dBm to RMS voltage conversion. P (dBm) = 10 log 10 (v 2 / (R*p 0 )) Where p 0 is the reference wattage and is 1mW or 1x10 … But, if we add by 10dBm then add by 3dBm, we have added a total of 13dBm, using just 3's & 10's! 0dBm = 1mW +3dBm = x2 _____ 3dBm = 2mW (we're not done yet) 3dBm = 2mW +10dBm = x10 _____ 13dBm = 20mW So, 13dBm equals 20mW.
