adrv9026 use case 44 updata error and Multiple power on Tx phase jumps

Category: Software
Product Number: 0
Software Version: adrv9026 Transceiver Evaluation software 6.4.0.17

(1) When we use ADRV9026 use case 44 configuration, we are unable to update graphs,We will directly apply the Use case 44 configuration to the project, but the power consumption is too high. How can we reduce power consumption under this configuration?

How to change the filter order in the configuration?

(2)We adjusted the parameters of use case 44, and the software can update Graphs and Gernate Profile. However, our board was powered on multiple times and found that the Tx phase was unstable, with a jump of about 10 degrees. How can we solve this problem?

The parameters we adjusted are:

Tx Input Sample Rate 61.44

Tx RF Synthesis Bandwidth 48

Tx Primary Signal BW 40

ORx RF Bandwidth 45

choose DPD HB1 Enable 

choose DPD HB2 Enable 

Tx int factor 8

Rx Dec factor 32

ORx Dec factor 20

thanks!

  • I'm not sure if i understand the issue exactly.

    What do you mean by directly applying the use case to the project? 

    User has to fix the profile in the GUI, generate resource files and use them as is for the bring up.

    Which filter? Why do you want to change it? What issues are observed?

    How did you measure the phase? The phase on the same channel is varying from boot to boot? Did you enable RF phase synchronisation?

    FYI, with 61.44 MSPS IQ rate, DPD is not supported.

    Please let us know the exact issue, logs, how you are measuring so we can help you better.
