IWR1843 - Single-Chip 76- to 81-GHz FMCW mmWave Sensor

Datasheet Summary

Description

The IWR1843 device is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operating in the 76- to 81-GHz band with up to 4-GHz continuous chirp.

The device is built with the low-power 45-nm RFCMOS process from Texas Instruments.

Features

  • FMCW transceiver.
  • Integrated PLL, transmitter, receiver, Baseband, and ADC.
  • 76- to 81-GHz coverage with 4 GHz available bandwidth.
  • Four receive channels.
  • Three transmit channels.
  • Ultra-accurate chirp engine based on fractional- N PLL.
  • TX power: 12 dBm.
  • Built-in calibration and self-test (monitoring).
  • Arm® Cortex®-R4F-based radio control system.
  • Built-in firmware (ROM).
  • Self-calibrating system acro.
