    Hello,
    

    ADRV9029 has 4 ORX Paths.
    In relation to this, I have the following questions:
    

    1. Is Tx Power Detection possible using ORX Path?
    2. If possible, is Tx Power Detection possible even in sections where DPD is not operating (when there is no traffic)?
    

    At first glance, it seems that Mean ORX Power does not change if DPD is not operating.
    

    thank you

      Q1) Yes, Possible. If you know the ORX feedback path loss, you can estimate the Tx power.
      

      Q2) Yes. You can read the ORX dec power and based on the ORX feedback path loss, you can estimate the Tx power.
      

      Big said:

      Whether you have DPD running or not, mean ORX power would not change as long as the temperature and ORX attenuation is same. Due to temperature, the signal chain may have gain variations.
