Tee Attenuator Calculator
Enter Attenuation and Zo to solve for R1 and R2 Tee Attenuator
Atten. (dB) Zo () R1 () R2 ()
2.88 433.34
R1 = Z0 * ((10 ^ (dB / 20) - 1) / (10 ^ (dB / 20) + 1))
R2 = 2 * Z0 * (10 ^ (dB / 20) / (10 ^ (dB / 10) - 1))
Pi Attenuator Calculator
Enter Attenuation and Zo to solve for R1 and R2 Pi Attenuator
Atten. (dB) Zo () R1 () R2 ()
869.55 5.77
R1 = Z0 * ((10 ^ (dB / 20) + 1) / (10 ^ (dB / 20) - 1))
R2 = (Z0/2) * (10 ^ (dB / 10) - 1) / (10 ^ (dB / 20))
