Fairview Microwave's Pi Attenuator Calculator (aka Pi pad attenuator) allows you to determine the Resistor values (R1 & R2) for a Pi attenuator (measured in Ohms).
The Pi attenuator (Pi pad) is a specific type of attenuator circuit which resembles the shape of the Greek letter "Π" (Pi). The Pi attenuator consists of one series resistor and two parallel shunt resistors to ground at the input and the output. Visit Fairview Microwave's RF coaxial attenuators page for product details.
**Note: All of our calculators 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.
