Integrated circuit packaging configurations for terahertz active sensing

A radar device, comprising:

• a substrate defining a plane extending in a first direction and a second direction substantially orthogonal to the first direction;
• a transmitter comprising a transmit integrated circuit mounted on the substrate, comprising:
• a first conductive layer comprising a transmit antenna array, the transmit antenna array comprising a plurality of transmit RF antennas;
• and
• a transmit semiconductor die disposed between the first conductive layer and the substrate and having integrated thereon transmit circuitry configured to cause at least some of the plurality of transmit RF antennas to transmit first RF signals having a center frequency in a range between 150 GHz and 1.5 THz;
• and
• a receiver comprising a receive integrated circuit mounted on the substrate, the receive integrated circuit comprising:
• a first conductive layer comprising a receive antenna array comprising a plurality of receive RF antennas;
• and
• a receive semiconductor die disposed between the first conductive layer and the substrate and having integrated thereon receive circuitry configured to receive, via the plurality of receive RF antennas, second RF signals generated, at least in part, by reflection of the first RF signals off of a target object.
