can you help me to study adaptive predistortion
I want to find out kinds of adaptive technique, and how to connect adaptive to predistortion.
Now I study RF predistortion not Digital redistortion,because I can't program.So I hope there is a kind of adaptive with no digital.
Please upload some book about it or tell me which books I need to look at.
Wait for your help, thank you.
I think that adaptive solutions need digital solutions to determine errors. You need to learn to program if you want to play in this field. You might want to start with
High Linearity RF Amplifier Design, Peter B. Kenington
Advanced Techniques in RF Power Amplifier Design.Steve C. Cripps
to get an understanding of this.
Joel Dawson wrote "Feedback Linearization of RF Power Amplifiers" which covered an analog approach, but his results were poor, and it's not obvious that the approach will yield better solutions.

thank you ,Dave. This is a predistortion modle
But I want to ask how to set Out of Band Filter ,because input two different frequency to test IMD, for example ,I use WCDMA 2110~2170MHz ,Surpose I input 2110 and 2130MHz or input 2110 and 2150MHz . How can I set my Out of Band to get 3rd IMD and transfers to Power Detector
