Abstract
The disclosure relates to a radar transceiver having a transmitter comprising a phase shifter. Example embodiments include a radar transceiver (200) having a normal mode of transmitter operation and a self-test mode of operation, the transceiver (200) comprising: a digital controller (116) configured to provide a digital control signal indicative of a phase shift; a digital to analogue converter (122) configured to receive the digital control signal and provide an analogue signal in accordance with the phase shift; a phase shifter (124) configured to receive the analogue signal and provide a phase shifted output signal for transmission; a dummy load (240) connected to receive the analogue signal from the digital to analogue converter (122) and to provide an analogue output; a resistor network (331) connected across an output of the dummy load (240); a testing module (335) configured to measure the analogue output of the dummy load (240); and a controller module (339) configured to control operation of the dummy load (240), testing module (335) and digital controller (116) during the self-test mode of operation by: enabling the dummy load (240); operating the digital controller (116…
