Fractional Bandwidth Calculator Review

Absolute bandwidth (f₂ – f₁) tells you the raw span in Hz. But —the ratio of that span to the center frequency—tells you how “wide” the system truly is relative to where it operates.

For waveguide or cavity filters, fractional bandwidth also influences Q-factor and insertion loss. Low FBW = higher Q, narrower tuning range. fractional bandwidth calculator

🔹 FBW (%) = (f₂ – f₁) / f_center × 100 where f_center = (f₁ + f₂) / 2

– next time you spec a bandpass filter or design a log-periodic antenna, let the calculator do the heavy lifting. Low FBW = higher Q, narrower tuning range

Ever designed a filter, antenna, or amplifier and wondered: “How wide is my band, really?”
