Infineon begins mass production of 8Tx8Rx imaging radar MMIC
Infineon Technologies has begun mass production of the RASIC CTRX8188F, an 8Tx8Rx radar transceiver designed for next-generation 4D and HD imaging radar systems. The device is the automotive industry’s first production-ready MMIC to support centralised radar architectures, where raw sensor data is transmitted directly to a central vehicle computer for processing.
The move towards centralised architectures is expected to reduce system costs while improving radar performance compared with traditional edge-processing approaches. The CTRX8188F has been engineered to support edge processing in combination with Infineon’s AURIX TC45 microcontrollers and is aimed at advanced driver assistance systems (ADAS) and autonomous driving platforms.
Based on Infineon’s second-generation CMOS technology, the transceiver delivers improved RF performance at lower cost and offers industry-leading signal-to-noise ratio and noise figure characteristics. The device supports 4D and HD imaging radar applications capable of detecting vehicles and vulnerable road users at distances of up to 400 metres.
The CTRX8188F also meets the RF requirements of China’s Level 2 ADAS GB safety regulations and supports Level 2+ applications, making it suitable for one of the world’s fastest-growing automotive markets.
Designed as a scalable platform, the transceiver supports cascading configurations beyond 32Tx32Rx channels, allowing developers to address applications ranging from entry-level ADAS to high-end autonomous driving systems. A configurable CSI-2 interface provides compatibility with existing and emerging SerDes and Ethernet communication technologies, simplifying integration with central vehicle processors.
To accelerate development, Infineon also offers its CARKIT radar development platform, supporting both centralised and edge radar architectures with software tools, example code and a graphical user interface.
