Pi Attenuator and T Attenuator Calculator

This online calculator allows you to quickly determine the value of resistors in a Pi attenuator or T attenuator circuit. Just enter the desired attenuation (in dB) and impedance (Z) to calculate the needed resistors (R1 and R2) values.

This tool uses the following equations for Pi attenuator:

K = 10(attenuation / 20)
R1 = Z × ((K + 1) / (K - 1))
R2 = Z / 2 × (K - 1 / K)

This tool uses the following equations for T attenuator:

K = 10(attenuation / 20)
R1 = Z × ((K - 1) / (K + 1))
R2 = Z × (2 × K / (K² - 1))
