DC to RF efficiency of an ideal class-F amplifier is:
- A. 100%
- B. 78.4%
- C. 50%
- D. <80%
Answer: A. 100%
Explanation: DC to RF efficiency of class F amplifier is 100% which is achieved by using an infinite number of harmonics to yield square and half-wave sinusoid waveform shapes at device drain for voltage and current respectively.
