Good question. If something needs to be done and can be done, there is generally a well-known technique (or even a specific chip) to do it. I have never heard of multiplying frequencies to such a level before so, as your question suspects, there is likely another way (correct way or possible way) to achieve the OP's end goal.Generating 40MHz from 400Hz is a very strange requirement.
What is this for?
The solution is called a radio transmitter. 400Hz is in the audio range, so it's no problem for a standard microphone or line-in signal. Finding a 40MHz transmitter shouldn't be too hard. Baby monitors and old cordless phones were at 49MHz, if I recall.Is it possible to take a 400hz signal and multiply it to 40Mhz?
How can this be achieved and is there a packaged device that can be purchased to achieve this as easy as possible? Thx
