IWR6843AQGABL wireless transceiver chip TI original stock
explain
IWR6x43 device is an integrated single chip millimeter wave sensor that can operate in the 60GHz to 64GHz band and is based on FMCW radar technology. The device is manufactured by TI's low-power 45nm RFCMOS process, and achieves excellent integration in ultra small packages. The device is an ideal solution for low power consumption, self monitoring and ultra precision radar systems in the industrial field. A variety of models are currently available, including devices meeting functional safety standards and non functional safety devices.
