You can also use this to calculate how much attenuation you need if, for instance, you have a 2.0 volt input level and you need to attenuate it to 0.2 volts to prevent input overload. The given power attenunation in dB is 1.25 and the power destination is 9 W Find the power source in W. Simply change the value of given dB and power source for new calculation Where: Ap= Power Attenuation, or Power drop of signal transmission due to over long distances. This calculator provides configuration data for logarithmic stepped attenuators or logarithmic ladder networks. Such relay-plus-resistor networks are used for volume control in audio electronic devices, as a replacement for traditional analog potentiometers. This page aims to provide practical help for configuring this type of attenuators.Feb 01, 2006 · 30 watts = 10 Log (30,000 mw) = 44.8 dBm 44.8 dBm + 15 dB safety margin - 30 dBm max input = 29.8 dB attenuator So you want a combination of attenuators that add up to at least 30 dB. The attenuator (s) that you connect directly to your 30 watt source had better be rated to handle that power (they will have big heat sinks attached to them). For example, you can calculate the gain needed to raise the output level from 0.775 volts to 1.4 volts. You can also use this to calculate how much attenuation you need if, for instance, you have a 2.0 volt input level and you need to attenuate it to 0.2 volts to prevent input overload. The closest I can find are 20 watt, 2.5 Ohm and 20 Ohm resistors - will they be ok? Rob, If we take those values, we'll have: 20 ohms in parallel w/ 8 ohms = 1/ (1/20 + 1/8) = 1/ (0.05 + 0.125) = 5.71 ohms in parallel. 2.5 ohms (series resistor) + 5.71 ohms = 8.21Ω total. As you can see, it's extremely close to the 8Ω total we need. vundabar meaning xa
