    Abstract: In an embodiment, a method for determining the phase shift between a first signal and a second signal includes: delivering the first signal to a first input of a 90° hybrid coupler; delivering the second signal to a second input of the 90° hybrid coupler; determining a first piece of information relating to a power of a first output signal delivered to a first output of the 90° hybrid coupler; determining a second piece of information relating to a power of a second output signal delivered to a second output of the coupler; and adjusting the phase of the second signal until obtaining a calibrated phase for which the first piece of information is substantially equal to the second piece of information, wherein the first and second signals have identical frequencies, and wherein the phase shift between the first signal and the second signal is equal to the calibrated phase.

    Abstract: In an embodiment, a circuit includes first, second, and third 90° hybrid couplers coupled between first and second antenna terminals, a pair of low-noise amplifiers (LNAs), and a pair of power amplifiers (PAs). The pair of LNAs is configured to receive first signals from the first and second antenna terminals and has an output configured to be coupled to a receive path. The second coupler is configured in power combiner mode for receiving the first signals. The pair of PAs is configured to transmit second signals via the first and second antenna terminals and has an input configured to be coupled to a transmit path. The third coupler is configured in power divider mode for transmitting the second signals.

    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.

    Abstract: An embodiment electronic device comprises at least two antennas for transmitting signals, and at least one transmission path, the transmission path including a first coupling stage including a power divider, variable-gain power amplifiers, and a second coupling stage including a power combiner. Each coupling stage includes two inputs and two outputs, the two inputs of the first coupling stage being configured to receive a power input signal. Each output of the first coupling stage is connected to a different input of the second coupling stage via the variable-gain power amplifiers, and each output of the second coupling stage is connected to a different antenna. A controller is configured to control the gains of the variable-gain power amplifiers according to the characteristics of the power input signal, the signals transmitted by the antennas, and the coupling stages.
