9.1 Overview

The AWR2243 device is a single-chip highly integrated 77-GHz transceiver and front end that includes three transmit and four receive chains. The device can be used in long-range automotive radar applications such as automatic emergency braking and automatic adaptive cruise control. The AWR2243 has extremely small form factor and provides ultra-high resolution with very low power consumption. This device, when used with the TDA3X or TDA2X, offers higher levels of performance and flexibility through a programmable digital signal processor (DSP); thus addressing the standard short-, mid-, and long-range automotive radar applications.
