Hi Riccardo, thanks for the link - I prefer the most basic version. But like in all other papers I know the problem of the first positive drive pulse after applying the DC power is ignored - perhaps
Hello Tom, most schoolbook class-E designs assume a DC feeding choke with infinite inductance i.e. a huge inductor that keeps the DC current constant without any RF ripple. This is of course totally
Hej Johan, thanks for your budding info! I would be glad to get these documents concerning the DC feed inductor. Perhaps you´ll find some additional information about the shunt capacitor problem too?
Hi Tom, Why do you secide for a class-E at all? Do you see any actual advantage over a class D? 73, Stefan Am 09.10.2018 17:49, schrieb DK1IS: Hej Johan, thanks for your budding info! I would be glad

Hi Tom, the keyed PSU sounds like a good way to go considering your very slow keying speeds! I'm also attracted by the combination of simplicity and ultimate efficiency of single ended class E but ke
LF, Roger, Mal gave some insightful comments re: Class-E I have also used a class-E amp on 500kHz,and I echo all the comments about careful choice of FET and of the output tuning/loading to get the c
Hello Tony, I'm still using a Derivative of the Design from G3YXM's class E 1KW TX on LF If you refer to the TX in http://www.wireless.org.uk/136rig.htm : this is a class D TX, not class E. I am also
Tony The G3YXM designs are class D and not class E. I do not know of any amateur using class E except myself. There could be others of course but most favour class D probably because they are more fl
Ref recent discussion on the subject. I use a class E pa on 500 kcs and never get any trouble. As a general guide use high voltage fets and the fet V should be rated at about 5 times the supply V
