Abstract (en)
[origin: WO2020152400A1] Disclosed is a method for detecting the phase (Φ1) of an analogue signal (SA1) via a hybrid coupler (CH1) operating in a power combiner mode, the hybrid coupler (CH1) comprising a first input (BE1) intended to receive the analogue signal (SA1), a second input (BE2) intended to receive a reference signal (SREF) having a reference phase (Φ2) and a same frequency (FREF) as the analogue signal (SA1), and two outputs (BS1, BS2), and configured to respectively generate, at these two outputs (BS1, BS2), a first output signal (SS1) and a second output signal (SS2), comprising a measurement of the peak values (A1, A2, A3, A4) of the analogue signal (SA1), of the reference signal (SREF) and of at least one of the first and second output signals (SS1, SS2), a calculation of the phase-shift (Φ1-Φ2) between the phase (Φ1) of the analogue signal and the reference phase (Φ2) as a function of the measured peak values (A1, A2, A3, A4), and determination of the phase (Φ1) of the analogue signal (SA1) as a function of this calculated phase shift (Φ1-Φ2) and of the reference phase (Φ2).
