Abstract

The present disclosure relates to a radar transmitting device, comprising a CMOS transceiver chip configured to provide at least one local oscillator signal at an output of the CMOS transceiver chip, and at least one BiCMOS transmitter chip coupled to the CMOS transceiver chip. The BiCMOS transmitter chip has an input for the local oscillator signal, at least one amplifier coupled to the input, a plurality of outputs for outputting a radar transmission signal on the basis of the local oscillator signal, and a plurality of transmission paths between the input and the plurality of outputs. Each of the transmission paths has a controllable analog phase shifter for controllable beam scanning during emission of the radar transmission signal. Additionally or alternatively, individual transmission paths of the BiCMOS transmitter chip can be selectively activated or deactivated using control signals.
