The invention relates to a method for calibrating the centre frequency (FC1) of a hybrid coupler (CH1) operating in power-splitter mode, the hybrid coupler (CH1) comprising two inputs (BE1, BE2), two outputs (BS1, BS2), a capacitive module (MC1) coupled between the inputs (BE1, BE2) and the outputs (BS1, BS2) or on each input (BE1, BE2) and each output (BS1, BS2), the capacitive module (MC1) having an adjustable capacitive value (C1) making it possible to adjust the centre frequency (FC1), which comprises outputting a first reference signal (SREF1) having a first reference frequency (FREF1) on a first input (BE1) of said hybrid coupler (CH1), measuring the peak value (VC1) of a first signal (S1) output at a first output (BS1) of the coupler (CH1) and the peak value (VC2) of a second signal (S2) output at the second output (BS2) of the coupler (CH1), comparing the two peak values (VC1, VC2) and adjusting the capacitive value (C1) of the capacitive module (MC1) until obtaining equal peak values (VC1, VC2) to within a close tolerance.
