Design Guide

Wafer Chip-Scale Package 60GHz mmWave Sensor Reference Design for Industrial Applications

Description

This reference design targets applications requiring smaller form factor and low-power consumption. The design is based on TI's IWRL6432W, 60GHz mmWave radar device and uses a four-layer PCB stack-up with FR408HR material from Isola®. The reference design also has a smaller form-factor counterpart without debug and evaluation interfaces.
