SUMMARY
Class F amplifiers operate primarily in saturation and cutoff modes, rather than linear mode. The design of these amplifiers aims to minimize power loss during switching, which occurs when the transistor is not fully on or off. For power levels between 10W and 25W, understanding the operational characteristics of Class F amplifiers is crucial for efficient performance. The reference paper from Cree provides in-depth insights into the behaviors of Class F and Class F1 amplifiers.
