For example, an ideal class F amplifier
with only the second harmonic voltage short-circuited and one third-harmonic current peaked realizes a maximum drain efficiency of 75 percent.

Proper amplifier design coupled with electromagnetic simulation make it possible for the antenna to present an output impedance that is optimized at all the harmonics of interest, thus yielding an integrated Class F amplifier
