Calculation of power attenuators

Attenuators If larger power must be processed, on this webpage one can calculate the necessary power dissipations for individual resistors. Since no coils or capacitors are used, the matching takes place frequency-independently. Attenuators are suitable therby for the wide-band matching.


dB a =


Pi    T


Ω, PR1 = W

Ω, PR2 = W

Ω, PR3 = W

If you want to know, how looks the equations used into the script, then see at the mathematical background: resistors, power dissipations.
