Abstract: A method is provided for controlling the matching of an antenna to a transmission path. The transmission path includes an amplifier stage coupled at an input or at an output to the antenna and to a resistive load. The method includes performing a checking phase by measuring a first current temperature at or in proximity of the antenna and a second current temperature at or in proximity of the resistive load, triggering a matching of the impedance seen at the input or at the output of the amplifier stage in the presence of a first condition involving the first and second current temperatures, and then stopping the matching of the impedance in the presence of a second condition involving the second current temperature.

Abstract: In accordance with an embodiment, a connector is mechanically configurable between a wireless radio frequency transmission and a wired radio frequency transmission via a cylindrical dielectric radio frequency waveguide. The connector includes: a first package assembled to a printed circuit board provided with a radio frequency antenna; and a second package configured to be assembled to the waveguide, wherein the second package is configured to be removably assembled to the first package in the wired radio frequency transmission configuration and is separated from the first package in the wireless radio frequency transmission configuration.

Abstract: In an embodiment method, a hybrid coupler comprises a first input receiving an analog signal, a second input receiving an additional analog signal phase shifted by 90° from the analog signal, and first and second outputs. The method comprises injecting into the second output a test signal having an initial test phase, iteratively generating a current test phase for the test signal, from the initial test phase to a final test phase equal to the initial test phase increased by at least one portion of one complete revolution, and, in each iteration, measuring the current peak value of the first output, and storing the current test phase and the current peak value as a maximum/minimum peak value if there is not a stored maximum/minimum peak value higher/lower than the current peak value, respectively, and determining a phase of the analog signal from the stored test phase.

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.
