Predictive DPD virtual test bench

Next up in this series on modulated signals is an example of multi-dimensional EM design challenges: RF power amplifiers (PAs). Digital pre-distortion (DPD) is a favorite technique for linearizing PA performance. Static effects are easy to model and correct, but PAs are notorious for interrelated dynamic effects spoiling … Read More
