Single-chip FM-CW radar low-cost production test

In order to realize the low product cost potential of a single-chip FM-CW radar MMIC (monolithic microwave integrated circuit), an innovative production testing concept is developed in which the complete transmit/receive transfer function is verified in under one minute using the self-generated microwave signal in a simulated radar range environment. The test acceptance criteria are related to fundamental radar module specifications. The test environment, test acceptance criteria, and data storage are controlled by a personal computer. A text example is given. >
