    hi to everybody
    please somebody help me to design this circuit that its diagram shown in picture

    and more information and drawing in pdf files,

    i have to simulate this diagram in proteus

    these link for pdf files

    this sounds like homework. I could help a little but if its homework then giving you the answers won't teach you too much.
    pdf files can be created by alot of programs. usually its as simple as importing a photo into a pdf creator and typing the text.
    anyway let us know if this is homework so we can help teach you

    yes that is something like homework, but its really hard as homework and i cant understand more thing from that patent and i dont know how simulate it in proteus!?? more devices not exist in proteus library,or maybe i couldn't find them

    It was impossible to not be intrigued by this so I tracked down the patent. After reading the description and tech data I can't help but wonder what the benefits are over conventional AM. Unless I've misinterpreted its end function it seems like an overly complicated way of synthesizing common amplitude modulation, with no apparent benefit to justify the complexity. Admittedly, there's quite a bit of reading there and my eyes did begin to glaze. The AM signal to the RF Final seems analogous to a DAC.

    Perhaps the goal is audio power reduction? An RF final is a class C power amp. As such conventional Plate, Collector, or Drain modulation requires considerable audio power to modulate the carrier.

    Anyone else have any thoughts?

    Your instructor is a sadist.
