Texas Instruments IWR6243 Single-Chip FMCW Transceiver

Texas Instrument IWR6243 Single-Chip FMCW Transceiver can operate in the 57GHz to 64GHz band. The device enables unprecedented levels of integration in an extremely small form factor. IWR6243 is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in the industrial space.

IWR6243 is a self-contained FMCW transceiver single-chip solution that simplifies the implementation of Radar sensors. It is built on TI’s low-power 45nm RFCMOS process, which enables a monolithic implementation of a 3TX, 4RX system with built-in ADC converters and PLL. Simple programming model changes can enable various sensor implementations (Short, Mid, Long) with the possibility of dynamic reconfiguration for implementing a multimode sensor.
