Sorry, but I think that you need a better plan.
With those values for L and C, you are trying to operate at about 500 MHz.
Even if you can get it to oscillate at that frequency, which is questionable, the lack of frequency stability would make it next to useless. In any event, that value for C would be completely swamped by the stray capacitance of the antenna and the rest of the circuit.
This is the sort of simple AM transmitter operated at medium wave frequencies, with a range of a few meters, for demonstration purposes.
I don't know what the radio regulations are like in your part of the world, but I would certainly not trying to plug something like that into any sort of power amplifier.Does this circuit works?please help guys?
That circuit looks like someone put all the bits in a box, shook it up, emptied them out on the table and drew in the connecting wires.
It'll certainly cane your battery pretty quickly. What with all the unwanted harmonics it's going to generate, you probably will be able to pick it up on any receiver no matter what station it's tuned to; but only within a range of about 5 centimetres. Plug it into a power amplifier of any class except C, and you can expect nearby electrical appliances to begin malfunctioning horribly.
5nH || 20pF resonates at 503MHz, which is in the TV broadcast band.
No, it will not. You have no oscillator. Modulation method is atrocious. If you actually could get the last stage to oscillate, then you would have more FM than AM. You can not connect a modulated stage to a Class C stage except to provide pre-modulation drive. Under those circumstances, the Class C stage needs to be modulated as well.
Try again.
