Radar sensors are an integral part of advanced driver assistance systems (ADAS) in modern cars. While radar sensors are especially vital for autonomous vehicles, they also improve safety and comfort features for drivers as well. Radar sensors for cars are typically deployed for blind spot detection (BSD), lane change assistance (LCA), collision mitigation (CM), parking aid (PA), and rear cross traffic alert (RCTA) features. Infineon offers a wide variety of automotive radar sensors including short-, mid-, and long-range radar sensors.

As part of our comprehensive XENSIV™ family of sensors, we offer a range of RASIC™ 77/79 GHz front-end radar sensor ICs specifically for driver assistance systems, such as adaptive cruise control and collision warning. Capable of detecting and recognizing objects at a range of up to 250 meters, these RASIC™ solutions enable the driver assistance capabilities required to obtain a five-star rating from Euro NCAP (European New Car Assessment Program). In fact, our 77/79 GHz SiGe RASIC™ chips lead the MMIC segment. The RASIC^TM 77/79GHz automotive radar support ASIL C, reducing customer R&D efforts.

Complementing our 77/79 GHz offering, we also deliver the market’s most integrated 24 GHz radar transceiver family in the market, offering board savings of around 30 percent compared with discrete lineups. These automotive radar sensors can be used to build RF front-end modules for mid- and short-range radar applications in different configurations.

Moreover, Infineon offers a highly integrated 60 GHz radar transceiver which offers the most power and cost-effective solution for our customers. Used predominately for in-cabin monitoring systems, our 60 GHz portfolio enables our customers to achieve multiple functionalities by using a single 60 GHz radar setup. For instance, these sensors allow for the development of child presence detection inside the car which is a safety relevant feature to protect children from being locked and left behind resulting in a dangerous health risk scenario. Seat belt reminders are another add-on feature which is enabled by our 60 GHz radar products.

Infineon’s BGT60ATR24C has been designed for ultra-short range applications with best in-class jitter performance, ultra-low power consumption, wideband operation and robustness.
XENSIV™ BGT60ATR24C is a fully integrated radar transceiver operating in the frequency band from 58 to 62 GHz. It is a state-of-the art radar chip featuring 2 transmit channels, 4 receive channels, a low noise Phase Locked Loop (PLL), an integrated anti-aliasing Loop Filter (LF), sequencer and finite state machine for ramp generation, integrated RX baseband including Analog to Digital Conversion (ADC), sensor ADCs for temperature and power monitoring – all within a single chip. The digitized time signals are forwarded via the SPI interface to the application controller where they are being processed further.
