Pi Pad RF Attenuator Calculator with Formulas

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).

We have a large library of radio frequency calculators, including conversion calculators, RF product calculators and general RF calculators. Our free-for-general-use radio frequency calculators allow designers and engineers an easy-to-use tool that converts complex mathematical formulas to simple conversions. Pasternack’s complete range of radio frequency/microwave and millimeter wave calculators with formulas, including metric-standard, link budget, coax cable, power, attenuation, frequency and plenty others, provide you with the correct figures that you need for all your engineering requirements.

Our calculators are designed to provide solutions to real-world challenges. These include link budget, coax impedance, RF power conversion (such as dBm to Watts), attenuation, frequency, wavelength, VSWR/return loss, torque, noise, Free Space Path Loss (FSPL), unit conversion, microstrip and plenty more. Every calculator page includes a diagram or illustrated depiction of what the calculator is used for, besides providing you with a mathematical formula for that chosen calculator.

Our product-oriented calculators can also help you narrow down your search to the right product. Simply key in the desired variables and the calculator will highlight a ‘Find Related Products’ button that will showcase all the featured products that match your search criteria. The large number of RF calculators, conversions and formulas is part of our online technical resource library and complements the Engineers Resource Center section.
