Abstract: A transponder-based module is placed on a mobile object so as to transmit information in proximity to a reading device. The transponder-based module includes at least one energy source for supplying the transponder-based module, at least one sensor for performing measurements of a physical parameter, and a microcontroller linked to the measurement sensor for processing the measurements of the sensor. The module further includes a memory unit for storing the measurement data of the measurements performed by the sensor, a receiver of an interrogation signal from a reading device in proximity, and a transmitter for transmitting measurement data stored at ultra-high frequency and at very high bitrate subsequent to the reception of an interrogation signal from the reading device in proximity.

Abstract: A transmitter-receiver includes an electronic chip a mixer for mixing the frequency of a received radio frequency signal with that of an oscillating signal supplied by a first frequency synthesizer in, a switch having two inputs connected to an output of the mixer and to an auxiliary input terminal, a filter and gain stage connected to the output of the switch, and a modulator-demodulator connected to the output of the filter and gain stage. The first frequency synthesizer is connected between the output of the modulator-demodulator and radio frequency input and output terminal, and configured to supply a frequency-modulated signal to the radio frequency input and output terminal. The electronic chip further includes a second frequency synthesizer connected between the output of the modulator-demodulator and an auxiliary output terminal, and configured to synthesize a modulated low-frequency signal supplied by the auxiliary output terminal, whereby the center value of the low frequency is equal to the value of the intermediate frequency.
