Question

Why class e is used insted of class f power amplifier?

Answer 1

Answer:

The class-E/F amplifier is a highly efficient tuned switching power amplifier used at radio frequencies.

It uses a single-pole switching element and a tuned reactive network between the switch and the load.

Answer 2

Answer:

Class F amplifiers resemble class E amplifiers, but use a more complex load network. In part, this network improves the impedance match between the load and the switch. Moreover, it's designed to eliminate the input signal's even harmonics so the switching signal is more nearly a square-wave.
