Novel Approach for Wideband VNA by Sixport Principle

Authors: Tomáš Urbanec


Paper presents simple sixport principle and its frequency bandwidth. The novel multisixport approach is presented with its possibilities, typical parameters and frequency bandwidth. Practical implementation is shown with its measurement parameters and calibration. The bandwidth circa 1:100 is obtained.

Keywords: wideband, microwave measurement, sixport, VNA
