Overview
The Texas Instruments IWR1443FQAGABLR is a single-chip millimeter-wave (mmWave) sensor based on Frequency-Modulated Continuous Wave (FMCW) radar technology. This device operates in the 76 GHz to 81 GHz band with up to 4 GHz continuous chirp, making it an ideal solution for low-power, self-monitored, and ultra-accurate radar systems in various industrial applications. Built using TI’s low-power 45nm RFCMOS process, the IWR1443 integrates a 3TX, 4RX system with built-in phase-locked loop (PLL) and analog-to-digital converters (ADCs), enabling high levels of integration in a small form factor.
