Infineon BGT60ATR24C Automotive Radar Sensor

XENSIV™ 60GHz radar sensor for automotive sensing

The Infineon BGT60ATR24C is an automotive 60 GHz radar sensor that enables ultra-wide bandwidth FMCW operation in a small package. Sensor configuration and data acquisition are enabled with a digital interface and the integrated state machine enables independent data acquisition with power mode optimization for lowest power consumption.

The core functionality of BGT60ATR24C by Infineon is to transmit frequency modulated continuous wave (FMCW) signal via one of the two transmitter channel (TX) and receive the echo signals from the target object on the four receiving channels (RX). Each receiver path includes a baseband filtering, a VGA, as well as an ADC.

The digitized output is stored in a FIFO. The data are transferred to an external host, microcontroller unit (MCU) or application processor (AP), to run radar signal processing.


  • 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)
  • Full duplex FIFO structure as data buffer (196 kbit = 8192 words x 24 bits)
  • Linear Feedback Shift Register (LFSR) test pattern generator on chip for data transfer check
  • 8 to 10 bits sensor ADC for power and temperature measurement
  • Standard SPI mode for configuration and status register read accesses
  • Dedicated power modes for power reduction
  • An external 80 MHz reference oscillator is used as a system clock source
  • BITE (Built in test equipment) for EOL test in production at Infineon to verify RF performance
  • ChipID block provides info regarding the digital code version, the RF block version, and the RF configuration
  • Fabricated with BiCMOS Infineon process technology
  • Housed in a eWLB package
  • AEC-Q100/101 qualified
