There is provided a radio transceiver device. The radio transceiver device comprises an antenna. The radio transceiver device further comprises a signal processing module. The radio transceiver device further comprises a receiver chain configured to receive a first signal. The receiver chain extends from the antenna to the signal processing module and at least comprises an analog-to-digital converter (ADC), and is thereby configured to receive a first signal from the antenna and provide the first signal to the signal processing module after application of analog-to-digital conversion in the ADC to the first signal. The radio transceiver device further comprises a transmitter chain. The transmitter chain extends from the signal processing module to the antenna and at least comprises a digital-to-analog converter (DAC), and is thereby configured to receive a second signal from the signal processing module and provide the second signal to the antenna after application of digital-to-analog conversion in the DAC. The DAC is configured to generate a dither signal and is connected to the receiver chain for application of the dither signal to the first signal before application of analog-to-digital conversion in the ADC to the first signal.
