Balanced Attenuator Calculator - RF Design Tool

A Balanced Attenuator Calculator that takes attenuation in decibels and characteristic impedance as inputs and outputs the resistor values needed for a balanced (balanced) attenuator pad. Users enter the desired attenuation level and system impedance, and the tool returns the specific resistor resistances required to build a balanced attenuator network. The result is ready for immediate use in RF circuit design and impedance-matched pad sizing. Fairview Microwave hosts this calculator as a free resource, requiring no account or paid subscription to access the computation. Compared to other balanced attenuator calculators online, Fairview’s version is embedded directly within a large RF components retailer’s site, offering a streamlined interface focused on quick resistor value lookup without additional design coursework. While other tools may emphasize design formulas or H-pad/O-pad configurations, this calculator specifically targets balanced attenuator resistor calculation for RF workflows. It is presented alongside Fairview’s product inventory, making it a convenient stop for designers who also need to source matching components.
