ADRV9029/26 EVB Power

Whats your DPD tracking calibration configuration? You can try optimising the parameters such as Regularization value, Peak search window size, change the DPD update mode (2 for GaN PA) etc. Also, you may do a model sweep to identify the best model for your PA

Hi Ramarao

I was going through ADRV9029 data sheet and have found following paragraph page(128):

"The DPD is optimized for power amplifiers with rms output powers in the 250 mW to 10 W range"

I need to used for two amplifiers in a balanced configuration for get 42dBm (ideally), it will be higher than 10w. will DPD be still working for this power level?

Yes, there is no such restriction on the output power level from the DPD perspective. DPD will work for your target output power.

many thanks 

Hi Ramarao

1-DPD tracking calibration configuration?  how many mode for calibration we have

2- how to set the "Regularization value"? Please

3- How to set the "Peak search window size"?

Best Regards

Regularization value, Peak search window size,

Hi all

I have this configuration as shown below

I set my signal Generator 3.5Ghz and 100Bandwith 

which is received by ADRV _RX1 

and I transmitted by using TX1 as shown before

 The problem when I tried revive the signal through the ORX1 by suing TES software

 when i switch ORX on i got 

and 

I lost signal from TX1 direct

 please could you help me why this happen and how to avoid this error?

Best Regards

Is your TX output is connected back to ORX path?

Can you just feed an RF signal at the ORX input and check if the spectrum is observed in the GUI?

The TX should not disappear when ORX is ON, can you check if the RX got turned off by mistake from the sig. gen?

Hi Ramarao

Is your TX output is connected back to ORX path? Yes mate

Can you just feed an RF signal at the ORX input and check if the spectrum is observed in the GUI? I working on these

The TX should not disappear when ORX is ON, can you check if the RX got turned off by mistake from the sig. gen?(TX on because i can see the o/p in spectrum analyzer.) 

TX-ON, RX-ON  just when i switch on ORX every thing change to off.

an you just feed an RF signal at the ORX input and check if the spectrum is observed in the GUI?
