Abstract: A device is provided for electromagnetic shielding an electronic component and for dissipating heat generated by the component. The component includes a package designed to be fastened to a first face of a printed circuit, called a rear face, by a heat sink, the heat sink passing through the rear face of the printed circuit and emerging on a second face of the printed circuit, called a front face. The device includes a metal structure mounted on the front face of the printed circuit and defining an electromagnetic shielding enclosure. The metal structure having a first heat discharge opening lying approximately opposite the heat sink. The device further includes at least one thermal connector, a first end of which is fastened to the metal structure and a second end of which is fastened to the heat sink and/or to the front face of the printed circuit near the heat sink.

Abstract: A method is provided for obtaining a calibration frequency for calibrating a transmission chain that can transmit information signals on a frequency band comprising a plurality of channels. The chain includes an amplifier that can be configured according to at least one gain configuration. The method includes: obtaining an output power value of the amplifier; obtaining a frequency dispersion, based on the power value; detecting whether a constraint linked to said frequency dispersion is satisfied; and if the constraint is not satisfied, then obtaining a current frequency subband and a calibration frequency for said current frequency subband.

Abstract: A method and apparatus are provided for calibrating an information-signal transmission line that includes elements for generating a control signal and transmitting information signals controlled by the control signals, and an amplifier of the information signals. The amplifier can be configured according to at least a first gain configuration associated with a first gain value, and a second gain configuration associated with a second gain value. The method includes obtaining, for each of the first and second gain configurations, first and second sets of initial values of the control signal, that correspond to first and second sets of measured power that overlap, and selecting, for each power-recovery setpoint value to which corresponds a first measured-power value of the first set and a second measured-power value of the second set, from the first and second calibrated values of the control signal, the calibrated value that meets a predetermined criterion.
