3 Description
The AWR2188 device is an integrated single-chip FMCW transceiver capable of operation in the 76GHz
to 81GHz band. The device enables unprecedented levels of integration in an extremely small form factor.
AWR2188 is designed for low power, self-monitored, ultra-accurate radar systems in the automotive space.
The AWR2188 device is a self-contained FMCW transceiver single-chip device that simplifies the
implementation of Automotive Radar sensors in the band of 76GHz to 81GHz. The device is built on TI’s
low-power 45nm RFCMOS process, which enables a monolithic implementation of a 8TX, 8RX 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 device including reference hardware design,
software drivers, sample configurations, API guide, and user documentation.
