    Question about RF power meter

    Hi guys, I want to build a new EMF meter but EMF meters are limited they can work around 60 hz, they can detect wider range but still not enough for me, so I wanted to change my direction and build a power meter for all range detection. Which diode is good for all bands or which kind of circuit? Any suggestions?

    Use AD8307, AD8313, AD8362, etc. of ADI.

    My goal is detection for much wider range like gamma rays.

    Re: Question about RF power meter

    The grid dip meter is a useful instrument for radio enthusiasts. It's popular because it's possible to build your own from a few discrete components.

    With a filter you can stop it from responding to ambient mains hum. Or you can plug in various coils in order to make it respond to a particular range of frequencies.

    Thanks but I am not sure it's for x and gamma rays.

    No it's not.

    You have been asking for RF power meter. X or gamma rays aren't RF although they are all electromagnetic radiation. Visible light or heat radiation is also electromagnetic, but not detectable with antennas or "RF" detectors.

    You should get at least a broad idea about the different ranges of electromagnetic spectrum and what kind of receivers can be suitable to detect one or the other.

    Really I didn't know what is gamma rays, thanks man. there is no need to playing with words, I said first EMF meter, It must be an RF meter too that's why I said RF meter also.

    Re: Question about RF power meter

    Maybe you start width designing an antenna for that bandwidth, then share your findings

    Cool, I know what's your point but noting is impossible bro, this thread is exactly for it so that's why I asked to others.

    Re: Question about RF power meter

    000SHREDDER000, we are not being obstructive or critical but you original question was very misleading. When you said you wanted a range wider than 60Hz people assume you are looking for something with slightly higher frequency capability. What you ask for in post #3 is for a bandwidth thousands of millions of time wider, way more than anyone was considering. The technology for measuring gamma rays is completely different to the technology for measuring 60Hz!

    It was rather like you asked for an instrument to measure the thickness of a hair then afterwards said it also had to measure the width of the solar system.

    Brian.
    PLEASE - no friends requests or private emails, I simply don't have time to reply to them all.
    It's better to share your questions and answers on Edaboard so we can all benefit from each others experiences.

    Exactly that's why I am here.
    I know it's uncommon but my information is so much lower than you that's why I asked here for finding an answer. It's possible or not.

    Re: Question about RF power meter

    emf meters on the market have separate detectors for low frequency magnetic field (coils), low frequency electric field (high impedance sensor) and MHz to GHz RF. To detect ionizing radiation like X- and gamma rays, you need a Geiger-Mueller tube.

    I know about it but geiger tube are only for gamma and x-rays. I heard about some of RF circuits that they can detect gamma rays also so I think it's possible without giger tubes.

    It is not circuits.

    What band of frequency do you want to detect ?
