If ignoring loss: Port A ratio = ( 10/100 = 0.10 ) (10%), Port B = ( 50/100 = 0.50 ) (50%) → remaining 40% lost? That’s not a passive splitter; it’s a directional coupler with a termination. A proper splitter calculator would flag this inconsistency.

[ \textPower Ratio = \fracP_\textoutputP_\textinput ] If ignoring loss: Port A ratio = ( 10/100 = 0
A is a specialized tool (online or manual) that determines the required splitter values based on input levels and desired output levels, or vice-versa. It is indispensable for engineers, network technicians, and installers to ensure impedance matching, minimize signal loss, and maintain system balance. 2. Core Mathematical Principles 2.1 Power and Voltage Ratios For RF and fiber optic systems, splitter ratios are based on power, not voltage. The fundamental formula for power ratio (in linear terms) is: [ \textdB = 10 \times \log_10(\textPower Ratio) ]
