Description

The AWR1243 device is an integrated single-chip FMCW transceiver capable of operation in the 76- to 81-GHz band. The device enables unprecedented levels of integration in an extremely small form factor. AWR1243 is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the automotive space.

The AWR1243 device is a self-contained FMCW transceiver single-chip solution that simplifies the implementation of Automotive Radar sensors in the band of 76 to 81 GHz. It is built on TI’s low-power 45-nm RFCMOS process, which enables a monolithic implementation of a 3TX, 4RX system with built-in PLL and A2D converters. Simple programming model changes can enable a wide variety of sensor implementation (Short, Mid, Long) with the possibility of dynamic reconfiguration for implementing a multimode sensor. Additionally, the device is provided as a complete platform solution including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
