Class E RF amplifier - Build (2/3)

#193 In this video I continue talking about the Class E amplifier by building and testing out the circuit that was simulated in Part 1. I go trough the various tests intended to verify the circuits operation and try to figure out what are the various limitation of the thing I built.

Thank you so much for doing this. My (tr)uSDX QRP HF transceiver uses a Class E output stage, and in my efforts to properly tune it up for maximum efficiency on each of its 5 bands I have learned quite a bit on the practical level, but I really wanted to learn the fundamental theory of Class E designs so I could do it right, or even design my own Class E RF stage.

The ringing frequency is reduced by the damping factor from resonance: f = f_0 sqrt( 1 - zeta^2 ). Resistance slows down the current flow making it take longer to charge/discharge C.

Thanks 😁

Really nice.
Thanks!

nice👍

Why did not you use a SI5351 as input?

[@FesZElectronics]

This is a very interesting component, but I never used this part in the past. I guess, for the purpose of experimenting, it was easier to work with a dedicated signal generator, but in a final device, this sort of part- the SI535, would be better since its so compact.

пс... не боись, я проверил в двух переводчиках, это можешь прочесть только ты, его это не заденет, нейрональные сети переводчиков тут бессильны ;) ...
