Linearization of power amplifiers by means of digital predistortion has widely been researched for more than lasttwo decades, with applications to microwave bands. With increas-ing demands for spectrum, the use of millimeter frequencies isexpected in the future. In order to implement digital predistortionat millimeter-wave frequencies, well calibrated transmitter andfeedback receiver is necessary.This paper describes the most important signal processingalgorithms and their practical implementation in in-house built MATLAB-controlled setup aimed for research and evaluation fordigital predistortion algorithms in 60 GHz band.
