Description
AI
The AWR2243 device is an integrated single-chip FMCW transceiver capable of operation in the 76GHz to 81GHz band. The device enables unprecedented levels of integration in an extremely small form factor. AWR2243 is designed for low power, self-monitored, ultra-accurate radar systems in the automotive space.
The AWR2243 device is a self-contained FMCW transceiver single-chip device that simplifies the implementation of Automotive Radar sensors in the band of 76GHz to 81GHz. The device is built on TI’s low-power 45nm RFCMOS process, which enables a monolithic implementation of a 3TX, 4RX system with built-in PLL and ADC 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 device including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
