www.qrp4fun.de Calculation of attenuators

Attenuator If the output level of a stage is too high, in order to be led directly to the input of another, one scolded attenuators between them. On this webpage you can calculate the resistors for it. Since no coils or capacitor are used, the matching takes place frequency-independently. Attenuators are suitable therby for the wide-band matching.

But only rarely resistors are available in the calculated values. Change the calculated resistors against from you used and see, which deviations with it to arise.

If you want to know, how looks the equations used into the script, then see at the mathematical background: resistors, input resistor, loss and SWR.
