Infineon Technologies BGT60ATR24C XENSIV 60GHz Automotive Radar MMIC
Infineon BGT60ATR24C XENSIV ™ The automotive 60GHz radar sensor realizes ultra wideband frequency modulated continuous wave (FMCW) operation, and adopts small package. BGT60ATR24C is designed for on-board occupancy detection (scanning the cabin to scan people and pets). The sensor configuration and data acquisition are realized through the digital interface. The integrated state machine supports independent data acquisition, has power mode optimization function, and can achieve low power consumption.
The core function of BGT60ATR24C is to transmit FMCW signals through one of two transmitter channels (TX) and receive echo signals from target objects on four receiving channels (RX). Each receiver path includes baseband filtering, video graphics array VGA, and analog to digital converters (ADC). The digitized output is stored in the FIFO. The data is transmitted to the external host, microcontroller unit (MCU) or application processor (AP) to run radar signal processing.
