Low-power, ultra-wideband millimeter wave, and ultra-small form factor sensors
Applications include robotics, traffic monitoring, human detection, and factory automation.

Mouser Electronics is stocking the IWR1843 industrial radar sensor from Texas Instruments (TI).
The IWR1843 is an ultra-wideband millimeter wave (mmWave) sensor manufactured in TI's low-power 45nm RFCMOS process and is targeted for applications such as intelligent robotics, traffic monitoring, people detection and counting, building and factory automation, and material handling.

It also offers a high level of integration in an ultra-small form factor that is employed in self-monitoring, low-power, and ultra-accurate radar systems.

It is a frequency-modulated continuous wave (FMCW) radar sensor integrated on a single chip that operates in the 76–81 GHz millimeter wave spectrum and has three transmit (TX) channels, four receive (RX) channels, a built-in phase-locked loop (PLL) and an ADC, enabling monolithic execution.

Additionally, it integrates a digital signal processor (DSP) subsystem based on TI's high-performance C674x DSP to process the laser signal, as well as a built-in self-test (BIST) processor subsystem responsible for radio configuration, control, and calibration. The user-programmable Arm Cortex R4F processor, which is mounted on the board, enables object tracking and classification, AUTOSAR, and interface control.
