Infineon — BGT60ATR24C Automotive Radar Sensor

Features

• Integrated LDOs from 1.8 V to 1.5 V to supply the digital domain
• RF-Frontend at 60 GHz covering frequencies from 58.0 to 62.0 GHz with two TX and four RX channels
• Baseband chain consisting of high pass filter, low noise voltage gain amplifier (VGA), and antialiasing filters
• Four ADC channels with 12 bits resolution and up to 4 MSps sampling rate to sample the RX-IF channels
• Integrated RF-PLL, timers, counters, and FSM to run set of frames in standalone mode (no communication with AP required except first trigger and raw data transfer)
