Digital Predistortion for improved EVM Performance

The scope of this application note is to give a comprehensive guide on how the R&S®FSW signal and spectrum analyzer with the option R&S®FSW-K18 may be used to create a Hammerstein model for the R&S®SMW200A vector signal generator’s output stage. This model can then be applied to counteract inherent non-linearities and memory effects and improve the Error Vector Magnitude (EVM) at high output powers of the R&S®SMW200A vector signal generator.
