Hello everyone, I would like to make this thread to ask for permission to discuss issues related to the Class E amplifier circuit.
"I am reading the concepts of the Class E amplifier circuit. The article is located at https://www.allaboutcircuits.com/technical-articles/how-to-tune-a-class-e-amplifier/ .Can anyone help me explain why Equation 1 is derived in the article?"

 

It looks to me like it is found thru experimenting with adjustments. I am thinking that is why there are so few equations presented.
