The basic idea of this thesis is a feasibility study on production capability of novel concepts for testing the automotive radar whose role has proven paramount in the course towards driving autonomy. Today, in multiple occasions, the soldering of semiconductor devices on test printed circuit board (PCB)s is required for testing or verification purposes. At the same time, the automated test equipment (ATE) is also being used widely for its many benefits, like reducing testing time and achieving multi-site capability. In this case, the device under test (DUT)s are not soldered but placed and kept still on specifically designed interfaces during testing. In this direction, a novel contact technology capable of radio frequency (RF) would prove extremely useful, so our interestwas focused on socket technology. A wide range of socket technologies is available right now by a variety of vendors. A feasibility study was proposed, regarding the evaluation of one of the most promising sockets in the market. The potential use of this new contact technology is expected to create new possibilities for further use-case scenarios, like frequency-modulated continuous-wave (FMCW)-related measurements for example. In order to facilitate use-case testing on ATE, a test concept has been suggested as the main focus of this thesis. Themain idea is based on a delay line approach, requiring the use of a rectangular waveguide (as the delay line) to simulate the round trip delay time of the electromagnetic wave of the radar, exactly as it would happen in a real-life driving scenario.
