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
At what frequency, are you measuring the output power? The EVB that you have is matched for Low band, Mid band or high band?
The output power also depends on the BB input waveform scaling that you are using.
For eg, if the PAR of the input waveform signal is 11dB and if you use -11dBFS scaling waveform, you could get an output power of 7(Max. power)-11 = -4dBm from the Tx.out.
Try testing with a CW tone initially.
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?
