RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Fixed Pi and T Attenuator Calculator

Enter values for Rin, Rout, and Attenuation, then click Calculate. If unequal termination resistances are used and an attenuation value is selected that is lower than what is physically possible (a negative resistor value is displayed), then a message will appear in the box over the schematics. "k" is the linear ratio equivalent to the decibel value of the attenuator.

Equations used in this calculator can be found on the Pi and Tee Attenuators Equations page.

Calculated values do not change until the "Calculate" button is clicked.
