IWR1843 - Texas Instruments

IWR1843 Single-Chip 76- to 81-GHz FMCW mmWave Sensor

The IWR1843 device is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operating in the 76- to 81-GHz band with up to 4-GHz continuous chirp. The device is built with the low-power 45-nm RFCMOS process from Texas Instruments. This solution enables unprecedented levels of integration in an extremely small form factor. The IWR.
