Would it be possible to share internal block diagram and internal schematic of the AD9361 device?
Please see: AD9361, AD9364 and AD9363 [Analog Devices Wiki]
Thanks Travis for your response. Would you please share link of the internal high-level schematic diagram
Those diagrams and those in the UG-570 document are all we provide for the transceiver.
Thanks Travis. Is there any way to monitor TX LO frequency and its amplitude?
With the Linux and No-OS drivers the TX frequency can be read from the device itself (Linux) or it is just part of the configuration structure (No-OS).
If you want to get the actual signal itself transmitted you can use the TX monitors, but they only function in TDD mode.
By using would it be possible to measure actual TX LO signal? I see that TX MON section resides on receiver section, would you please explain more on this how to measure actual TX LO signal on signal analyzer. Do we need to change register values to check the TX LO on MON ports, if yes what would be expected loss in the chain from TX LO output to TX MON ports?
The internal LO is not actually pinned out on the part. So you cannot observe it alone.
The TX monitors reuse the RX chains to provide measurements of the TX power, see the UG-570 doc for more info on how it works with circuit diagrams.
Can you give me more detail on what you are trying to do?
