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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

VSWR | Return Loss | Reflection Coefficient Conversion Calculator

VSWR Mismatch Errors - RF CafeThis Javascript 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 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.
