  • Method of calibrating the transmission chain of a wireless transceiver and corresponding wireless transceiver
    Patent number: 7804908
    Abstract: A calibration is performed tone per tone during interframe spacing. A peak detection is used for measuring the level of the corresponding signal, and a gain correction coefficient is stored for correcting the digital complex modulation coefficients provided by the mapping.
    Type: Grant

  • Direct-conversion receiver for a communication system using a modulation with non-constant envelope
    Patent number: 7095997
    Abstract: A direct-conversion receiver includes an analog stage for receiving an incident signal from a transmission channel, mixers and programmable-gain amplifiers. The receiver further includes at least one compensation module having input and output terminals respectively connected between the output of the mixers and the input of the programmable-gain amplifiers. The compensation module compensates for both a static DC voltage offset and a possible dynamic DC voltage offset of the analog stage.

  • Method and device for control of the transmission power of a cellular mobile telephone
    Patent number: 6980822
    Abstract: A cellular telephone includes a plurality of power amplifiers having a common operating region. If one of the amplifiers has to be deselected, a desired moment for the switching to another amplifier is defined based upon a predetermined transmission interrupt criterion. The power continues to be adjusted with the currently selected amplifier until the instant of switch over. Switching to the other amplifier may then be performed after the transmission has been interrupted.

  • Radio-frequency switching device, in particular for mobile cellular telephones
    Publication number: 20040022211
    Abstract: A radio-frequency switching device includes first and second radio-frequency channels connected to an input/output terminal. A controllable switching device selects one of the radio-frequency channels in response to a switching control signal. The switching device includes a respective control module connected to each radio-frequency channel. Each control module includes a PIN diode whose cathode is connected to the input/output terminal, and a control transistor whose base is connected to a control input for receiving the switching control signal. A conducting terminal of the control transistor is connected to the anode of the PIN diode.
