2 Introduction

The AWR294x is a single-chip mmWave sensor composed of an FMCW transceiver, capable of operation in the 76GHz to 81GHz band, radar data processing elements, and peripherals for in-vehicle networking. TI mmWave Sensors enable high-performance measurement and object detection over a variety of applications, but some designs require minimal power consumption. This application note discusses various power-saving techniques on the mmWave sensor, where power consumption concerns are critical. This guide helps users to implement various optimizations for evaluation. Moreover, this document discusses the tradeoffs involved as well. The power-saving techniques discussed in this document can be implemented exclusively through software.
