This work gives an overview of Six-port networks and implementation technologies. Furthermore, several state-of-The-Art calibration techniques are discussed, which are necessary to achieve accurate displacement measurements. The calibration techniques can be classified into four categories: calibration of baseband signals, I/Q domain calibration, phase linearization and detector linearization. Highest accuracy is obtained by a combination of two or more calibration steps.Conference Paper10.23919/MIKON.2018.8405341Other
