I am new at analog circuit design, so I need some help. I bought some Instrumentation Amplifiers: AD8421, AD8428 and AD8429 and the Evaluation board EVAL-INAMP-82Rz for them.
I want to test which InAmp is suitable for my application. In order to measure them, i need to provide a differential signal on the input of my Evaluation Board. My differential Signal should have 8MHz bandwidth.
I have a ROHDE & Schwarz HF-Synthesizer HM8134-3 that can create a single ended signal from 1 Hz to 1.2 GHz with -127 dBm to +13 dBm. (I also have a HUBERT A1020-75-250 High Frequency Amplifier, i dont know if i need that) Now I want to convert the single-ended-signal into a differential signal.
Is it possible to do that with some of the following Amplifiers:
AD8138 or AD8042 or ADA4941-1 or AD8475 ??
It should look something like this. Is this OK?
