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.

Abstract: A 90° hybrid inductive-capacitive coupling stage includes two first stage terminals capable of forming two stage inputs or two stage outputs and two second stage terminals capable of respectively forming two stage outputs or two stage inputs. The coupling stage is advantageously modular having a first stage axis of symmetry and a second stage axis of symmetry orthogonal to each other with neighboring inductive metal tracks being overlaid in at least one crossing region to form both an inductive circuit and a capacitive circuit. The metal tracks are coupled to the first stage terminals and to the second stage terminals such that the two first stage terminals are situated on one side of the first stage axis of symmetry and the two second stage terminals are situated on the other side of the first stage axis of symmetry.
