About this document
Scope and purpose
This document briefly describes the function, circuitry, and performance of the 60 GHz autonomous reference
design radar. The reference design provides the supporting circuitry to the on-board BGT60LTR11AIP
monolithic microwave integrated circuit (SiP) Infineon's 60 GHz radar chipset with antenna-in-package (AIP).
The board is fully functional in autonomous mode, for low cost and user-friendly applications.
