XENSIV™ 24 GHz pulsed-Doppler radar sensor for automotive sensing The XENSIV™ BGT24ATR22 is a Silicon Germanium Monolithic Microwave Integrated Circuit (MMIC) for 24 GHz automotive radar applications. It provides building blocks for analog signal generation and reception, operating in the frequency range from 24.0 GHz up to 24.25 GHz with 2 transmit channels and 2 receive channels. The analog baseband and the ADC are integrated. The whole radar sensor is controlled by a finite-state machine, which is optimized for independent radar operation with ultra-low power consumption.
