    Frequency
In summary, the individual needs a 10MHz sine wave voltage output at 3-6V, but their signal generator can only reach 1MHz. They are looking for suitable components and are also concerned about budget. They have searched online but have only found results related to processors. They mention using a resonance charger and don't need the frequency to be highly accurate or stable. They thank the person for their advice and mention using a signal generator IC. They also express concern about possible RF interference.

For some reason,I need to have a 10Mhz sine wave voltage output(I only need to deal with around 3-6V),but the signal generator I can use can only provide maximum 1MHz sine wave
I would like to ask if there are any component that is/are suitable
If possible,budget is a concern too
thanks

Actually I tried to search on the internet,but the results are just something like Mhz to Ghz used in processor or something

is this a one-off hobby project?

how accurate and stable do you need frequency?

check around on Ebay and the electronic surplus sites for an old HP 10544A time base.

It is used for resonance charger
As long as the frequency is high enough for that,maybe I don't need the frequency to be too accurate and stable(to be honest,even the frequency changer is good, the instruments I have are not good enough to match that LOL)
Thanks for the advice

there are inexpensive crystal controlled integrated circuits for computers and 10megahertz is not at all uncommon. but you'll have to filter it to get a sinewave.i used to frequent a hobby site called discover circuits, their forums are a great source of experimenter help. only resonance chargers i am used to are ferroresonant 60 hz transformer based...

Welcome to the PF.

You may be able to find a signal generator IC (like the ones that are used to make signal generator lab instruments) that will reach 10MHz on its sine output. 1MHz is more common, but there should be some that can make it up to 10MHz.

I do have to point out, though, that you need to be careful about launching energy at 10MHz -- that can cause harmful RF interference with other communication equipment and bands. It would take a pretty big antenna (or a many-turn coil...) to launch the EM wave at 10MHz though. What is your "resonant charger" like physically? Do you have any experience dealing with RF equipment and RF Interference (RFI)?
 

FAQ: Problem about changing frequency

What is frequency and why does it change?

Frequency is the number of occurrences of a repeating event within a specific time frame. It can change due to external factors such as temperature, pressure, and voltage, which can affect the speed of the repeating event.

What are the consequences of changing frequency?

Changing frequency can affect the accuracy and performance of devices that rely on precise timing, such as electronic circuits, communication systems, and power grids. It can also cause interference with other devices operating at different frequencies.

What methods are used to change frequency?

Frequency can be changed by adjusting the speed of the source of the repeating event, such as a generator or oscillator. It can also be changed by using frequency converters, which convert the frequency of an input signal to a desired output frequency.

What are some common applications that require precise frequency changes?

Precise frequency changes are crucial in various fields, including telecommunications, radio and television broadcasting, satellite navigation, and scientific research. They are also essential in industries such as healthcare, aviation, and military technology.

How do scientists measure and regulate frequency changes?

Scientists use devices called frequency counters to measure frequency changes accurately. To regulate frequency, they may use feedback systems, such as phase-locked loops, which compare the output frequency to a reference frequency and make adjustments to maintain a constant frequency.
