RF Pi Attenuator Calculator
Use this tool to calculate Resistor values for a Pi attenuator. Enter the desired value of attenuation and the characteristic impedance (default value is 50 ohm). Formula R1 = Zo [10dB/20 + 1] / [10dB/20 – 1] R2 = Zo/2 [10dB/10 – 1] / [10dB/20] where R1 is the shunt resistor and R2 is the … Read more
