In this work, a waveguide impedance generator based on the use of three motor-controlled metallic stubs, a monomode cavity loaded with water and PTFE cylinders is used to calibrate a waveguide ten-port reflectometer. Radial basis function neural networks are used to learn the relationship between the actual reflection coefficient and the power detectors' output. Results indicate that this impedance generator can be successfully used to calibrate the ten-port reflectometer. © 2010 Wiley Periodicals, Inc.
