Abstract :
A device and algorithm of measuring of antenna feeder complex reflectivity are presented. A microwave converter and low frequency switch are used. The first and third harmonics of the output detector signal are processed. All of that results in elimination of instrument components non-ideality and reaching of high equipment linearity.
