Abstract
Example embodiments describe a radio device for wireless communication and radar sensing, the radio device including: a transmitter configured to generate a modulated RF signal and to transmit the modulated RF signal via a transmitting antenna; and a receiver configured to receive a modulated RF signal via a receiving antenna and to down-convert the received modulated RF signal. The radio device additionally includes a selector unit configured to provide the receiver with a copy of the transmit modulated RF signal, or, a local oscillator signal for down-converting the received modulated RF signal, thereby enabling wireless communication and radar sensing operation.
