The Pi (pad) RF attenuator calculator allows you to determine the Resistor values (R1 & R2) for a Pi attenuator. Resistance in this calculator formula for pi attenuator is measured in Ohms. The Pi attenuator (Pi pad) is a specific type of RF attenuator circuit which resembles the shape of the Greek letter for Pi. The Pi attenuator consists of one series resistor and two parallel shunt resistors to ground at the input and the output. Consisting of one series resistor and two parallel shunt resistors; the benefit of our Pi attenuator calculator is it can help you determine and measure in Ohms each of the resistor values (R1 & R2).
**Note: Our calculators, like this Pi (pad) RF attenuator calculator with formulas, allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
