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 ...

This calculator converts between return loss (RL), voltage standing wave ration (VSWR), and reflection coefficient (Γ).
It also calculates the amplitude and phase error created by two imperfect impedances. Two VSWR values are taken as input.
Finally, VSWR improvement due to attenuation is calculated.
Numerical inputs are not error trapped. Absolute values of inputs are used for calculation.
Calculated values do not change until the "Calculate" button is clicked.
