Abstract
In an embodiment method for detecting the phase of an analog signal via a hybrid coupler operating in a power-combiner mode, the hybrid coupler comprises a first input intended to receive the analog signal, a second input intended to receive a reference signal having a reference phase and the same frequency as the analog signal, and two outputs, and is configured to generate, at these two outputs, a first output signal and a second output signal, respectively. The embodiment method comprises measuring peak values of the analog signal, of the reference signal, and of at least one of the first and second output signals, calculating the phase shift between the phase of the analog signal and the reference phase depending on the measured peak values, and determining the phase of the analog signal depending on the calculated phase shift and the reference phase.
