THS4304: Using THS4304 to amplify the uv voltage signal.

Part Number: THS4304

I want to use THS4304 to amplify the uv voltage signal.

My signal is almost 220MHz, 46uv pulse signal. I want to amplify it to 46mv. Maybe I need to use two THS4304 amplifiers to solve this problem.

Is there any reference design circuit to solve my problem? Or is there other amplifiers I can use?

Here is my simulation file. I want to amplify the output signal of this simulation file.

Thanks for your answer.8322.Noname.TSC

  • You probably want to use a 1st stage of OPA855 at say a gain of 20 followed by another stage at gain of 5 - Target say 400MHz in that 2nd stage so need at least 2GHz. GBP. or a current feedback device. Will need split supplies to get theOPA855 to work

    Actually, maybe just two stages of OPA855 at gain of 10 each would be the way to go.

    Thank you for your answer.

    Do you mean that I need two OPA855 to amplify the signal?

    Sorry, I can't understand your saying: split supplies to get the OPA855 to work. Can you give me a further explanation of that statement? Or some references?

    Maybe you can use the simulation files to make me understand.

    Thanks a lot.

    I should have opened you file first, 

    You need to use +/-2.5V on the OPA855 Zt stage, also, it is already rolled off quite a lot at 220MHz.

    Hello,

    Closing this thread as issue is being addressed in a different post.

    Best,
