Class C Amplifier with Eliptical Filtering

02:58:01

Eliptical low pass filter on the output. Thr class C amp is like in the previous circuit. Interestingly eliptical filters have an extremely sharp cut of after the cutoff frequency, but has some rejection wobbling after the cutoff. Anyway it does give very nice harmonic rejection. 

- Drawn Power - 5.45W
- Output Power - 3.4W
- Efficiency -  63%

Just for curiosity... How old are you? I have to say I'm quite curious about that

Interesting

Well I've been at it for 5 or 6 years. I was bound to learn so, although not to be redundant I'd quote my favorite Einstein saying. The more you learn, the less you know ;)

I found electronics to be quite interesting only a bit more that 2 years ago, when I started experimenting with electrochemistry. Since I will go to university because of the school I'm doing, it is quite possible I will do something whith electronics, but not sure about what yet (:

What're you studying?

Nice question XD. The course name is Liceo delle Scienze Applicate (applied sciences high school or something), it's kind a high school which should point on a wide but general understanding of sciences, even if it has very little laboratories, despise the name suggest, and the government cuted the money for those the year I started it. Nice XD

But I'm more into electrical engineering (specifically circuits and stuff)

I see, especially on amplifiers I noticed ; ) But, when you design a circuit, do you try it also in real life? (Just a nice way to ask you if you have a lack in components like me or not XD)

I do have a lack of components but what i need i gather, and yeah mostly in real life things don't turn out as in simula, but with a little tweaking it always turns out good. The problems with real life discrepancies is mostly in semiconductors. They have different threshold levels, internal resistances, hFe's and such and this may cause problems

Ok, so this doesn't happen only to me XD

Of course not. People like us are mostly scavengers, gathering components from old electronics and stuff
