1. Low-Loss Signal Requirements in Automotive Radar Systems Automotive radar and ADAS modules operate at 77–79 GHz frequencies, demanding minimal insertion loss and consistent phase integrity. Dense multilayer routing, compact stackups, and exposure to thermal cycles present challenges for signal fidelity. Megtron 6 PCBs, with Dk = 3.45 ±0.02 and Df = 0.002 @10...
