Discussion Overview

The discussion revolves around generating a 10MHz sine wave voltage output for a resonance charger application, particularly when the available signal generator can only provide a maximum of 1MHz. Participants explore potential components and solutions while considering budget constraints and the need for frequency accuracy and stability.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks components suitable for generating a 10MHz sine wave output, expressing concerns about budget and the limitations of their current signal generator.
  • Another participant questions whether this is a one-off hobby project and inquires about the required accuracy and stability of the frequency.
  • A participant suggests looking for an old HP 10544A time base on eBay or electronic surplus sites as a potential solution.
  • It is mentioned that inexpensive crystal-controlled integrated circuits can generate 10MHz, but filtering may be necessary to obtain a sine wave output.
  • One participant warns about the potential for harmful RF interference when operating at 10MHz and asks about the physical characteristics of the resonant charger and the user's experience with RF equipment.

Areas of Agreement / Disagreement

Participants express various suggestions and considerations regarding the generation of a 10MHz sine wave, but there is no consensus on a specific solution or component. Multiple competing views and approaches remain in the discussion.

Contextual Notes

Participants mention the need for frequency accuracy and stability, but the specific requirements are not fully defined. There are also concerns about RF interference that are not resolved in the discussion.

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)?
