Tee Attenuator Calculator

Tee Attenuator Calculator

Calculate the resistor values for a resistive tee attenuator using:
\[ R_s = Z_0 \times \frac{10^{\frac{A}{20}} – 1}{10^{\frac{A}{20}} + 1}, \quad R_p = \frac{Z_0}{2} \times \frac{10^{\frac{A}{10}} – 1}{10^{\frac{A}{20}}} \]

* Enter the desired attenuation (dB) and the system impedance (Ω).

Step 1: Enter Parameters

Example: 10 dB

Example: 50 Ω

Series Resistor: \( R_s = Z_0 \times \frac{10^{\frac{A}{20}} – 1}{10^{\frac{A}{20}} + 1} \)
Shunt Resistor: \( R_p = \frac{Z_0}{2} \times \frac{10^{\frac{A}{10}} – 1}{10^{\frac{A}{20}}} \)
