Abstract: The disclosure aims to implement an automatic frequency offset compensation of the frequency between emitter and receiver equipments, in radio frequency modules, with a frequency offset that can be larger than that the receiver can allow, without time loss and extra consumption. To solve this problem, the disclosure provides an automatic frequency offset compensation device comprising a reception front end, at least a filter, an I/Q demodulator for obtaining the I (In Phase) and Q (Quadrature) parameter, an automatic frequency control AFC unit for comparison of a received frequency with the real frequency of the equipment, and a microcontroller and a frequency synthesizer. In this device, the frequency offset is calculated by the AFC unit from the information given by the I/Q demodulator.

Abstract: A method of power management of an electronic device, the method including the steps of: sending periodically at least one signal by the microcontroller to a radio equipment in order to control an incoming radio frequency transmission after an inactivity time of the radio equipment, returning in standby mode of the microcontroller, initiating by the radio equipment of a power up sequence, powering up one by one the different functional blocks of the radio equipment, determining of a measurement of a received power of the incoming radio frequency transmission once a RSSI detection functional block is powered and determining a state mode of power consumption to apply to all the functional blocks of the radio equipment and the microcontroller functions of the comparison of the measurement to a reference threshold.
