3 Description

The IWR6243 is an integrated single-chip FMCW transceiver capable of operation in the 57- to 64-GHz band.

This 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 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 (Short, Mid, Long) with the possibility of dynamic reconfiguration for

implementing a multimode sensor.

Additionally, the device is provided as a complete platform solution including reference hardware design,

software drivers, sample configurations, API guide, and user documentation.
