Abstract: A hybrid coupler operating in a power divider mode includes two inputs, two outputs, a capacitive module coupled between the inputs and the outputs or on each input and each output. The capacitive module has an adjustable capacitive value making it possible to adjust the central frequency. A calibration method includes: delivering a first reference signal having a first reference frequency on the first input of the hybrid coupler, measuring the peak value of a first signal delivered to the first output of the coupler and measuring the peak value of a second signal delivered to the second output of the coupler. The two peak values are compared and an adjustment of the capacitive value of the capacitive module is made until an equality of the peak values is obtained to within a tolerance.
