Hi, in order for the class E to be operational, the switch of the transistor has to be on and off.

1. How to make the class E PA transistor become a switch? Is it we need to supply a vpulse voltage at the biasing of the transistor?
2. Input port in the PA design before the matching components already being supply with the sine wave at the resonant freq, how abaut vbias and vdrain of the class E transitor? is it supply with vdc or vpulse? Please advice. Thanks
