Receive only using ORx instead of RX

Thread Summary

The user inquired about configuring the ADRV9029 to use two ORx paths with 450 MHz bandwidth each instead of four RX paths with 200 MHz bandwidth. The final answer indicates this is not possible at their end. The ORx path is not designed for typical receiver use and lacks gain control, making it unsuitable for this application. The user planned to combine the 900 MHz bandwidth at the FPGA, but this configuration has not been tested.

Hi ADI,

In our application, there are time when we config the ADRV9029 to be a receiver only. So I want to know if we can use 2 ORx path, each one has 450MHz bandwidth, instead of 4 RX path with 200MHz bandwidth each, for receiving signals? And how to do it if it is possible?

Thank you.

  • Hi  ,

    I’m aware of the limitations with the ORX path, but theoretically, we should be able to achieve 900 MHz coverage using just 2 LOs and 2 ORX paths, right? We’d like to test this out. Could you guide us on how to configure the ADRV9029 to use only the 2 ORX paths for receiving simultaneously? The TX paths and TX calibrations could be turned off if needed.
