IWR1443 - Texas Instruments

IWR1443 Single-Chip 76- to 81-GHz mmWave Sensor

The IWR1443 device is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operation in the 76- to 81-GHz band with up to 4 GHz continuous chirp. The device is built with TI’s low-power 45-nm RFCMOS process, and this solution enables unprecedented levels of integration in an extremely small form factor. The IWR1443 is an ideal so.
