Splitter Ratio - Calculator

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

[ \textPower Ratio = \fracP_\textoutputP_\textinput ] splitter ratio calculator

[ \textdB = 10 \times \log_10(\textPower Ratio) ] Since splitters are passive, conservation of energy applies

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): Since splitters are passive

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