The radar transceiver assembly configured to reduce ghost lobes and narrow the receive beams so as to provide a better image resolution relative to current radar transceiver assemblies is provided. The radar transceiver assembly includes a first transceiver chip and a second transceiver chip mounted on opposite sides of the substrate. The accordingly, space on the first support surface may be utilized for antennas. The first array of transmit antennas and first array of receive antennas is interleaved with the second array of transmit antennas and the second array of receive antennas. The second array of transmit antennas and the second array of receive antennas are electrically coupled to the second transceiver chip via a coupling structure.
