Automotive Imaging Radar devices are a new upcoming market, targeting applications to detect and analyze object movements around the car. It brings promising new technology to automakers worldwide that enables more intelligent vehicles. These devices are part of a comprehensive driverless system that enables autonomous mobility. As a key part of sensing systems for automated driving, imaging radar will be an enabling element for automated driving features on highways and urban environments. Those devices are mmWave transceiver devices, operating in the 76 – 81 GHz frequency range. An innovative test solution has been developed, to allow the test of those devices at mmWave frequencies on the UltraFlexPlus test platform. The test solution, called DX81, consists of several compact modules placed in the DIB board application space. It allows bidirectional, transmit and receive DUT testing in the 76-81 GHz mmWave frequency range. It is a highly integrated, IGXL supported, suited for multisite high volume production test.
