mini dB-Calculator by DL5SWB

mini dB-Calculator is a compact, no‑nonsense utility designed to make decibel math fast and reliable. Developed by DL5SWB, it streamlines everyday calculations for RF, audio, and communications work—whether you’re at the bench, in the shack, or out in the field.

Key features

• Convert between linear ratios and decibels (gain/loss)
• Translate dBm and watts in both directions
• Work with voltage-based dB calculations using a chosen impedance (e.g., 50 Ω or 75 Ω)
• Add and subtract gains and losses to find net levels
• Convert between VSWR, return loss, and reflection coefficient
• Quick, readable results with a clean, lightweight interface

Ideal for radio amateurs, RF engineers, technicians, and students who need accurate decibel conversions without the overhead of a full engineering suite.
