8.1.2 Calculating Output Voltage Swing

This section gives a quick reference of the output voltage swings for different input power levels. In this example, the output is terminated with a 100‑Ω differential load and a power gain of 13 dB is assumed.

GUID-20220302-SS0I-74JW-TNPZ-WQ5N5JLSBQHR-low.svg Figure 8-2 Power and Voltage Levels
Equation 1. Voltage gain = 20 × log(Vo / Vi)
Equation 2. Power gain = 10 × log(Po / Pi) = 10 × log((Vo2 / 100) / (Vi2 / 50)) = 20 × log(Vo / Vi) – 3 dB
