I have ADRV9029/26 EVB depend on guide the power can be +_6dbm max how can i change the power output from TX port in 9026?Please
70MHz? Are you referring to 5G NR or any other application?
5G NR does not have 70MHz as far as i know.
Also, the measurement bandwidth is per 100MHz where as it should be 70MHz as the channel BW is 70MHz. To me, it looks like you are getting the output power as expected.
The steps to enable DPD are explained in the document available in the link
You can try to do a model sweep following the below link
Before doing the model sweep, you may try to use an existing model file and check the DPD performance.
Which PA are you using?
Can you do a DPD model sweep, get an optimised one and test with the same?
What is the raw ACLR of the PA? How much correction are you getting?
Can you please provide us the DPD tracking config. parameters and the DPD statistics?
What is the ORX gain Index?
Can you please test at 3dB backoff from the target power and check the DPD performance?
