The IWR2243 is an integrated single-chip FMCW transceiver capable of operation in the 76- to 81-GHz band. This device enables unprecedented levels of integration in an extremely small form factor. IWR2243 is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the industrial space.
IWR2243 is a self-contained FMCW transceiver single-chip solution that simplifies the implementation of Radar sensors. 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 ADC converters. Simple programming model changes can enable a wide variety of sensor implementation with the possibility of dynamic reconfiguration for implementing a multimode sensor. The IWR2243 device supports connection of multiple devices in cascade fashion. This enhances the angular resolution to meet high performance radar sensor development.
Additionally, the device is provided as a complete platform solution including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
