  • Method for digitally compensating variations, as a function of temperature, of an electrical quantity of an embedded space radiofrequency telecommunications equipment item
    Patent number: 9287842
    Abstract: A digital compensation method includes measuring the temperature of the equipment item and applying an analogue control voltage intended to maintain the electrical quantity of the equipment item at a predetermined setpoint value. At each measurement instant, the method includes interrogating look-up tables respectively associated with different setpoint values, then, when the measured temperature is situated between two digital temperature states stored in the look-up tables, creating intermediate digital temperature states situated between the two stored digital temperature states, computing, by interpolation, digital control words corresponding to the intermediate digital temperature states created, and selecting a digital control word, stored or intermediate, corresponding to the measured temperature, then delivering, to at least one of the N individual devices, the analogue control corresponding to the selected digital control word.
