Infineon Radar Transceiver Enables Centralized ADAS Architecture for 4D Imaging Radar

Infineon Technologies AG has officially started production of its RASIC CTRX8188F, a next-generation 8Tx8Rx radar transceiver designed to support centralized radar architectures for modern vehicles. The new Monolithic Microwave Integrated Circuit (MMIC) is the first solution in the market developed specifically for this architecture, marking an important advancement for automotive radar systems. Built to meet the growing performance demands of advanced driver assistance systems (ADAS), the Infineon radar transceiver is engineered to deliver high-resolution environmental sensing while remaining compatible with future vehicle electronic architectures.

The CTRX8188F delivers industry-leading signal-to-noise ratio and noise figure performance, enabling advanced 4D and HD imaging radar capabilities. These performance improvements allow vehicles to detect vulnerable road users and other vehicles at distances of up to 400 meters, supporting enhanced situational awareness in complex driving conditions. The device satisfies the RF performance requirements defined under the Level 2 ADAS GB regulation and is also suitable for Level 2+ applications, making it particularly attractive for manufacturers developing vehicles for the China automotive market.

Developed using Infineon's second-generation CMOS technology, the CTRX8188F supports highly scalable radar implementations with cascading configurations exceeding 32Tx32Rx channels. The device integrates a configurable CSI-2 interface that provides compatibility with both existing and next-generation SerDes as well as asymmetric Ethernet communication technologies. This flexibility enables automotive manufacturers to integrate the radar transceiver into a wide variety of centralized electronic architectures while supporting future platform evolution.

To simplify product development and accelerate customer programs, Infineon also provides the CARKIT radar development platform in multiple hardware configurations. The platform helps reduce engineering effort and development costs while enabling faster validation of radar applications. Productive samples of the CTRX8188F radar MMIC together with CARKIT development modules across different configurations are already available, allowing automotive developers to begin integration and testing immediately.
