3. Solid-state amplifiers and performance
In §

, we looked at the operation of a power transistor and its output matching conditions. However, describing the amplifier that incorporates this transistor also requires specifying the polarization (or power supply) conditions, which define the so-called operating class, giving access to an essential parameter, electrical efficiency.
Calculating the efficiency of an amplifier means estimating...
