2.3.1 AWR2243

The AWR2243 device is an integrated single-chip FMCW transceiver capable of operation in the 76 to 81GHz band. The device enables unprecedented levels of integration in an extremely small form factor. AWR2243 is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the automotive space.

The AWR2243 device is a self-contained FMCW transceiver single-chip solution that simplifies the implementation of Automotive Radar sensors in the band of 76 to 81GHz. It 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.
