Abstract
A method and a device for determining the amplitude and the phase of an impedance connected on a transmission line, including a bidirectional coupler having a first line interposed on the transmission line and having a second line providing at its respective ends two measurement signals, and a balun having its respective differential-mode inputs receiving data representative of the measurement signals.
