At present, most of the vehicle-mounted millimeter-wave radars are used in the United States and Europe, but now in the Torch High-tech Zone in Xiamen, there is also a high-tech enterprise that can independently develop millimeter-wave chips - Xiamen Yixing Semiconductor Technology Co., Ltd. Hereinafter referred to as 'Italian Semiconductor'). As early as January 2015, Yixing Semiconductor took the lead in independently developing the first 24GHz millimeter wave radar chip in China, and successfully put into mass production, filling the domestic gap.
Recently, the company's newly developed 1 to 2 millimeter wave radar chip has low cost, low power consumption and high performance. This means that more and more inexpensive millimeter wave radar sensor products will enter the future. In the daily life of ordinary people.
Millimeter wave radar makes driving safer
When you drive, do you have such an experience: Even if you play a 12-point spirit, but because the line of sight is blocked by the car body, forming a blind spot, some collisions are still inevitable. However, the millimeter wave radar blind spot monitoring system is installed in the car. After that, it becomes safer to drive, and the driver no longer has to worry about collisions with vehicles or pedestrians entering the blind spot.
This is because the vehicle's millimeter-wave radar can use the antenna to emit electromagnetic waves, detect the echoes reflected by the obstacles near the car, and then comprehensively analyze the radar signal processor to calculate the relative speed and distance of the car and the obstacle, and generate a warning. Information is passed to the vehicle control circuit to control the vehicle's transmission and brakes to respond to collisions.
'Millimeter wave radar has higher detection stability, longer working distance and better environmental applicability.' Dr. Yang Shoujun, general manager and technical director of Xiamen Yixing Semiconductor Technology Co., Ltd., compared with sensors such as ultrasonic, infrared, camera, etc. The millimeter wave radar has a long detection range, high precision, high resolution, and is not limited by temperature and light. It has the characteristics of working all day and all day.
In addition to being applied to on-board radars, millimeter-wave radars are widely used in security, intelligent transportation, drones, smart homes, etc. It can be said that millimeter-wave radar products have emerged and put into practical use, and more and more people have obtained A smarter and more convenient life experience.
'China Core' reduces the threshold of innovation in millimeter wave radar industry
Although the market of millimeter wave radar is huge, there are not many enterprises that have the ability to independently develop millimeter wave radar integrated circuits in China. As the earliest high-tech enterprise focusing on the design of civil millimeter wave radar integrated circuits, Yixing Semiconductor not only has world-class technology. R & D team and development environment, also has millimeter wave radar core hardware platform / program and core software algorithms, can provide the industry with low cost, high integration, high performance millimeter wave radar sensor overall solution.
In 2016, MSI SG24T1, the 24GHz transmitter of Italian Semiconductor, was honored to be selected as the 11th China Core's Most Potential Product Award and became one of the 16 products selected nationwide. In 2017, Yixing Semiconductor was re-elected in the 12th China Core's most investment-value enterprise is one of only five in the country, which fully reflects the comprehensive strength of Yixing Semiconductor in terms of independent innovation, market development, brand value and local industry status.
In addition, Yixing Semiconductor has also cooperated with the Xiamen Integrated Circuit Design Public Service Platform (XMICC) to create a professional laboratory for millimeter-wave integrated circuits. It has become one of the few microwave/millimeter wave development test platforms in the country, for millimeter-wave radar. The development of the industry is very important. The millimeter wave radar industry has high technical threshold and obvious characteristics. Xiamen has started early in this field. In the world, Xiamen can have a place, occupy the commanding heights and lead the development of domestic and foreign industries.
Recently, Yixing Semiconductor has released a 24GHz millimeter wave radar chip SG24TR12, which has lower power consumption, higher integration, more powerful functions, and simultaneous transmission and reception functions. 'This chip is smaller, use The field is even wider. 'Yang Shoujun said that Yixing Semiconductor will continue to increase the R&D investment in the field of millimeter wave radar chips in combination with the development of the Chinese market, and successively launch one full 4 integrated fully integrated millimeter wave radar chip, ' With 'China Core', more and more smart products will enter the homes of ordinary people at a more affordable price.'
