Sa. Chahine et al., A 6-PORT REFLECTOMETER CALIBRATION USING SCHOTTKY DIODES OPERATING INAC DETECTION MODE, IEEE transactions on instrumentation and measurement, 42(2), 1993, pp. 505-510
This work presents a six-port reflectometer in W frequency band (75-11
0 GHz) using Schottky diodes as power detectors. A linearization proce
dure and an AC detection technique are used to improve the measurement
accuracy. In addition, a calibration procedure requiring two standard
s, a matched waveguide and a short circuit, is described. A comparison
between experimental results obtained by the six-port reflectometer a
nd other automatic network analyzers is presented.
