Abstract :
The five-port reflectometer has been recently applied to demodulators and radars, offering an alternative to classic In-Phase/In-Quadrature (I/Q) discriminators. In these applications, calibration of the reflectometer is an important task. Most of the methods developed are suitable for the instrumentation and measurement field and present a high degree of complexity. We propose in this paper a new method for calibrating six or five-port reflectometers. This procedure is advantageous for its simplicity and is particularly useful for calibration in manufacturing processes.
