Abstract
A radio-frequency transceiver device includes a transmission circuit generating a transmission signal at a transmission pad connected to a transmission antenna by modulating a radio frequency signal as a function of a control signal. First and second reception circuits receive first and second signals at first and second reception pads connected to first and second reception antennas. The received first and second signals are demodulated via the radio frequency signal to generate first and second demodulated reception signals. A control circuit operates during a reception test phase to generate only the control signal in order to test, as a function of the first and second demodulated reception signals, whether the received first signal corresponds to the received second signal. A reception error signal indicating a reception error is generated when the test indicates that the received first and second reception signals do not correspond.
