Abstract
An integrated circuit for a radar device comprises at least one transmitter and at least one receiver. The integrated circuit comprises: a direct digital synthesizer, DDS, configured to output a control signal; and a multiplier configured to receive a local oscillator input signal and a further input signal from the DDS. In a first mode of operation, the DDS and multiplier cooperate to generate at least one transmitter signal to be transmitted from the radar device; and in a second mode of operation the DDS and multiplier cooperate to generate at least one low frequency modulated transmitter signal to be internally routed to the at least one receiver for calibrating the at least one receiver.
