    i am just design a envelop detector....input is given from FPGA 10nf to 20ns..
    i have to strech this pulse train in some millisecond..
    please suggest me...values of capacitor & resisto and which type of diode will give me desirable input...
    please tell me briefly..

    thank you.

    We need a lot more information to help with this,my friend.

    I assume you have a modulated envelope which you are detecting.
    If that part is working OK,we can probably address the pulse stretching problem separately.
    A lot of the people on this forum are more focussed on that area,rather than the RF part.
