DENSO Develops 24 GHz Automotive Radar Sensor Using TowerJazz's SiGe Technology

TowerJazz has announced that DENSO Corporation has used its 0.18 um advanced SiGe technology to develop a 24-GHz rear and side radar sensor. This sensor, developed using TowerJazz’s submillimeter-wave technology, is used in the Toyota Camry that was released in North America in July 2017 and will help enhance the vehicle's safety system.

DENSO’s rear and side radar sensor system offers SRR (short range radar), enabled by TowerJazz’s advanced SiGe process, which helps alert the driver of vehicles approaching from behind when changing lanes and when reversing. It also helps perform automatic braking when reversing. According to Global Market Insights, the global automotive radar market size is estimated to exceed $5 billion by 2023. The advent of self-driven cars is anticipated to drive industry growth over the forecast period.

DENSO chose TowerJazz’s SBC18 process as this technology combines high-performance SiGe transistors for the transmission and reception of the radar signal together with 0.18 um CMOS for the integration of digital control functions on a single chip. TowerJazz’s accurate models for first time success and automotive quality certification were also important factors in the decision.
