AD9363_Rx1x⇔Rx1x Isolation


I have one question. Please tell me.

The receiving system of AD9363 has two channels, RX1(A,B,C) and RX2(A,B,C).

The inter-channel isolation between RX1(A,B,C) ⇔ RX2(A,B,C) is described in the datasheet.

The isolation within the following channels is not described, so please let me know.

 ・RX1(A) RX1(B)、RX1(B) ⇔ RX1(C)、RX1(B)RX1(C)

 ・RX2(A) RX2(B)、RX2(A) ⇔ RX2(C)、RX2(B)⇔RX2(C).

Best Regards.

  • You cannot enable A,B,C ports at the same time. You can either enable A or B or C ports.

  • Hi srimoyi. Thak you for your reply.

    I am sorry for the lack of information. I am aware that it is not possible to enable ABC ports at the same time.

    As for the background of your question, the fact that there is no description of the attenuation of Rx1A, 1B, and 1C in the datasheet is due to the fact that the main signal is not affected by leakage.

    However, I would like to know if there is an estimate of the expected attenuation level, so I asked the question.

    Would it be possible for you to provide us with reference values of actual measurements or values obtained from calculations?

    Best regards.

  • We donot have the data for RX1A-RX1B/C isolation. Both the three A,B and C paths use the same path except the difference in LNA. If you are asking about the LNA gain, then for a particular gain index, all the three paths use the same gain(refer to RX gain table)
