Abstract :
Precise measurement of complex reflection coefficient and power sensor effective efficiency is reported using a reflectometer comprising two detectors and two directional couplers, one coupler having connected to it a reflector able to switch to different stable states. Results were obtained in three waveguide bands spanning 8.2-26.5 GHz.
