ADAR2004 Questions

Hi, my team and I are interested in ADAR2004 for our project.

We have the following questions and would like to seek the advice as we cannot find them from the datasheet.

  1. As we would like to use the part as a receiver, what is the spurious performance of the part?
  2. Since the input and output ports are of differential pairs, can i terminate + / - with 50ohms to use it as single ended port? Or must a balun be used?
    1. This is for the evaluation purpose as our equipment cannot support differential pair inputs and output;
  3. Please advise how we could evaluate this IC.

Thank you very much and have a blessed day!

    Hi JPLimAlex,

    1. This question is very broad and not easily answered in short form. I would suggest you get an evaluation board and test whatever spurious products you're interested in.
    2. You can terminate the unused input/output ports in 50Ω, but you'll see reduced performance for some specs. If you use an evaluation board to test the ADAR2004, it will have an SMT balun on the IF output port, so you'll only need to worry about the RF input.
    3. Order an evaluation board. I will email you instructions on how to do so.
