AD9361 TX linearization

Hello Guys


We would like to know how to optimally use an PA with the AD9361 part for non-constant envelope modulations.

For that we're thinking about TX linearization.


We want to somehow sample the TX signal from the PA output back and use that info.

So there are 3 questions:

  1. How (where in the device) to sample the TX signal?
  2. What mode to use for this optimization (using the max power output without distortion)?
  3. Are there some pre-distortion algorithms to use?
