#147 In this video I look at the basics behind the Class C amplifier. I have a look at how it works, how it behaves and what are some things to keep in mind when designing such a circuit. And to show things off, I also try to simulate the various behaviors and effects using LTspice. Further reading: Radio-Frequency electronics; J.
