The Class D RF amplifier - Design and calculations (2/3)
In this video I continue the series on the Class D amplifier by designing such a circuit. I go for the most basic voltage switching amplifier, but as always I still need some sort of output matching since that is the only way to get the desired output power. In the end I simulate the circuit and hopefully the real thing will behave in a similar fashion.
