Design files

Overview

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.

Features
  • Single 1.8V power rail
  • FR408HR based four-layer PCB stack up
  • Design dimensions:
    • IWRL6432W reference design: 89mm × 37mm
    • IWRL6432W small form-factor reference design: 12.6mm × 39mm
  • Low-power, low-cost 60GHz mmWave sensor using the IWRL6432W
  • Communication interfaces: UART, SPI, I2C and RS-232 - reference design has XDS110 debug probe and 60pin header for LVDS data capture
  • Antenna features:
    • Single element patch antenna array
    • 120° field of view
    • Angular resolution of 23° in azimuth plane and 58° in elevation plane
    • Human detection up to 15 meters at boresight
    • 4GHz bandwidth
