Excellent video, very precise and concise. Thanks!

Thanks Jeffrey. There is just a typo at RL > Ropt, where it should be "But not full current range".

Great video, thank you. I know it was posted a couple years ago, but if you're still checking comments, I was hoping you could clarify one thing- the load line impedance is not the same as the output impedance, is it? I ask because I'm designing a PA that outputs to a 42 ohm lossy transmission line that can be terminated with whatever I want. I can also size the transistor so the load line has the slope that I want, and if I can set it to say, 80 ohms (and terminate the transmission line with 80 ohms) but then impedance match S22 to the 42 ohms of the Tline, I could significantly reduce both drive current and DC current. Thanks!
