M. Caron et al., A VERSATILE EASY TO DO 6-PORT BASED HIGH-POWER REFLECTOMETER, The Journal of microwave power and electromagnetic energy, 30(4), 1995, pp. 231-239
A novel family of six-port reflectometers, designed in hybrid microstr
ip-waveguide technology, is presented for high-power applications. In
principle, there is no limitation in the input power level and the des
ign can be adapted for any waveguide frequency band. A prototype was d
esigned for the operational frequency of 2.45 GHz and measurements wer
e made as power levels up to 200 W. Thermo-dielectric characterization
was carried out on several well known liquids.
