Infineon Technologies has begun manufacturing the RASIC CTRX8188F, an advanced 8-transmit, 8-receive radar transceiver designed for the growing automotive 4D and high-definition imaging radar sector. Optimized for use with AURIX TC45 controllers, the production-ready chip supports edge processing and is the industry’s first radar MMIC capable of enabling centralized radar architectures. This approach allows raw radar data to be sent directly to a central vehicle computer for analysis, reducing system costs while delivering higher performance compared to traditional edge-processing systems. As demand for ADAS and autonomous driving technologies continues to rise, the CTRX8188F offers automakers and Tier-1 suppliers a scalable solution that balances performance, efficiency, and cost-effectiveness.
“The automotive radar market is at an inflection point. Centralized architectures are redefining how radar systems are designed, and the CTRX8188F positions Infineon and our customers at the leading edge of this transition,” says Dr. Frank Findeis, Head of RF business line at Infineon. “With the industry’s first productive 8Tx8Rx solution, we are giving Tier-1 suppliers and automakers a platform to speed up their ADAS and autonomous driving programs from entry-level assistance systems all the way to high-end imaging radar. This strengthens Infineon’s position as the partner of choice for customers developing centralized radar platforms at scale.”
The ADAS market is expanding rapidly, driven by regulatory mandates and consumer demand for higher levels of vehicle safety. The CTRX8188F is designed to help Infineon’s customers meet these demands. It delivers industry-leading signal-to-noise ratio and noise figure performance, enabling 4D and HD imaging radar systems capable of detecting vulnerable road users and vehicles at distances of up to 400 meters. The CTRX8188F meets the RF performance requirements of the Level 2 ADAS GB regulation ‘Safety Requirements for Combined Driver Assistance Systems in Intelligent and Connected Vehicles’, as well as Level 2+ applications. This makes it a compelling solution for customers targeting the Chinese automotive market, one of the world’s largest and most regulation-driven ADAS markets.
The CTRX8188F is the first production-ready 8Tx8Rx radar transceiver in the market, based on Infineon’s second-generation CMOS technology. This technology generation enables higher performance at lower cost compared to previous RF semiconductor nodes, strengthening Infineon’s competitive position in automotive radar silicon. The device supports cascading configurations even higher than 32Tx32Rx channels, enabling customers to address the full range of imaging radar system tiers from entry-level ADAS to high-end autonomous driving platforms within a single scalable product architecture.
A configurable CSI-2 interface ensures broad compatibility with existing and emerging SerDes and asymmetric Ethernet communication technologies. This simplifies integration with central processing solutions from major automotive SoC suppliers, reducing development risk and accelerating time-to-market.
To reduce customer development costs and shorten program timelines, Infineon offers the CARKIT radar development platform in multiple configurations. The CARKIT supports both centralized and edge radar architectures, enabling customers to evaluate and prototype system designs rapidly before committing to full program investment. Included software tools, example code, and a graphical user interface further reduce engineering resource requirements at the design stage, lowering the barrier to adoption of Infineon’s radar technology across customer programs of varying scale.
