Abstract: A phased array transceiver element comprises a local oscillator stage for generating beamformed in-phase and quadrature local oscillator signals, the local oscillator stage comprising a phase shifter connectable to a reference frequency source and applying a first phase shift; a primary frequency multiplier input from the phase shifter and applying a primary frequency multiplication factor; a phase-splitting arrangement input from the primary frequency multiplier and having a first output and a second output, the phase-splitting arrangement applying a second phase shift at the first output and a third phase shift at the second output; a first secondary frequency multiplier input from the first output of the phase-splitting arrangement, having an output for the in-phase local oscillator signal, and applying a secondary frequency multiplication factor; and a second secondary frequency multiplier input from the second output of the phase-splitting arrangement, having an output for the quadrature local oscillator signal, and applying the secondary frequency multiplication factor.

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.
