7.1.2 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 100Ω differential load and a power gain of 14dB is assumed.

TRF1213 Power and Voltage Levels Figure 7-3 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) – 3dB
