i need to generate an ac signal of frequency 10Mhz ...also i need current sufficent enough to light up 2-3 60w bulbs, wat shud i do?
colpitts oscillator seems to be an option..would sum1 care to elaborate about it.

 

can sum1 plzz post the specifications of the components of colpitts oscillator which would help me make this circuit...im a newbie..plzz help me out

 

Hello,

To let 3 bulbs of 60 watt light up, you will need a lot of power.

Here is a link on RF circuits.

And here on oscillators:

would the circuits provided in the link be able to sustain that amount of power (i mean the power sufficient dimly light up atleast a 60w bulb). i tried making a very trivial form of colpitts oscillator ,wen i connected it to a 8w bulb, the inductor got roasted to red.

 

Hello,

Take a look at this thread:

If you're not opposed to using high voltage, the most straightforward means is with a vacuum tube oscillator, using somethinig like an 811A.

This one uses 3 811's but you can get by with just one.
