  • Patent number: 9787351
    Abstract: A radiofrequency receiver device including: a local oscillator oscillating at an adjustable local frequency; a mixer receiving radiofrequency signals and the output of the local oscillator for the supply of intermediate-frequency signals; a filtering system configured and positioned to filter the signals according to a bandpath with an adjustable frequency bandwidth; and a data detector in the intermediate-frequency signals. It further includes means for adjusting the local frequency of the local oscillator, between minimum and maximum oscillation frequencies, and for adjusting the bandpath of the filtering system, between minimum and maximum frequency bandwidths, wherein the adjusting means are suitable for adjusting the local frequency and the bandpath until the detector detects a predetermined identification code in one of the intermediate-frequency signals.
