Splitter Ratio Calculator May 2026

1. Introduction In signal distribution systems—whether for radio frequency (RF), fiber optics, audio, or even fluid dynamics—a splitter is a device that takes a single input and divides it into multiple outputs. The splitter ratio defines how the input power (or flow) is distributed among these outputs.

[ P_\textinput = P_\textout1 + P_\textout2 + \dots + P_\textoutn ] Engineers use decibels (dB) to express ratios logarithmically: splitter ratio calculator

A 50:50 splitter gives a power ratio of 0.5 per port → (-3.01) dB per port. 2.3 Calculating Split Ratios Given a desired output power difference (e.g., tap value): splitter ratio calculator

[ \textdB = 10 \times \log_10(\textPower Ratio) ] splitter ratio calculator

Since splitters are passive, conservation of energy applies (ignoring insertion loss):
