Texas Instruments AWR2243 FMCW Transceiver
Texas Instruments AWR2243 FMCW Transceiver is a self-contained, single-chip solution that simplifies the implementation of Automotive Radar sensors in the 76GHz to 81GHz band. The AWR2243 offers unprecedented levels of integration in a minimal form factor. The AWR2243 FMCW Transceivers are ideal for low-power, self-monitored, ultra-accurate radar systems in the automotive space.
The TI AWR2243 FMCW Transceiver is based on TI's low-power 45nm RFCMOS process, enabling a monolithic implementation of a 3TX, 4RX system with built-in PLL and A2D converters. Simple programming model changes can allow various sensor implementations (short, mid, long), with the possibility of dynamic reconfiguration to enable a multimode sensor. The AWR2243 Transceiver is a complete platform solution, including reference hardware design, software drivers, sample configurations, an API guide, and user documentation.
