You must have missed my article in the early days about my class E and all the parameters, and especially monitoring the waveform V for correct operation. Things have moved on to class F and G but in
Although mainly HF focused, there is an excellent online discussion / forum on class-e transmitters that some may find of interest : http://classe.monkeypuppet.com/viewforum.php?f=1 Steve / VE7SL May
Undoubtedly I was and certainly I have. Your snide comments aside, I'm referring to your recent reported measurements and optimisation of tuning components to achieve good drain waveform as recounted
Mal, for proper class E operation, the drain waveform must be allowed to be non-symmetrical so you cannot just use a center tapped output transformer. In other words, there must be no "hard coupling"
Er....have I missed something...? I seem to remember several people responded when you asked the same question on Nov 4th. There were plenty of answers to your query about efficiency etc. with a few
I didn't miss it Mal... Nowhere have I seen your reported: DC Input Volts/Current RF Output Power Efficiency Others have replied to you with their own measured efficiency vs power so perhaps you can

Hi Johan Tnx for your observations and info on class E. connected in series, just use a single ended pa and choose the components to suit the power output required. The second harmonic and all other
MF and Co Getting suitable capacitors is the problem, not normally available from the junk box. Maybe a class F amp is the answer or the mechanical G turbo charged rumoured to be over 100% efficient
