About this app
Passive attenuators are two port / four terminal resistive networks that are designed to reduce (or attenuate, hence their name) the power between a source and load. They can also match the impedance between the source and load. They are used in a variety of audio and radio / RF applications. iAttenuation calculates resistor values for the following types of attenuator networks: Tee Network Pi Network H (Balanced Tee) O (Balanced Pi) Minimum Loss Pad Just enter in the input and output impedance values, and the desired attenuation, and iAttenuation does the rest! iAttenuation can also adjust the calculated resistor values to match the nearest standard 1%, 5%, or 10% tolerance values.
