China Automotive Network Munich, Germany Internazionale Semiconductor Corporation uses silicon - germanium - bipolar technology to develop a new type of chip, its operating frequency is 110 MHz, the operating speed is the highest in the world.
To date, such high operating frequencies have only been achieved with chips made of gallium arsenide. However, gallium arsenide is expensive compared to silicon materials. For this reason, researchers have added germanium atoms to silicon materials when developing this chip, successfully solving the problem of silicon materials used in high-frequency chips. The chip's switching time is very short, only 3.7 picoseconds, which is equivalent to 1 centimeter of light running time.
According to reports, this new type of switch circuit is mainly used for communication technology, such as radio communication transceivers, electrical equipment and computers WLAN communication. In addition, it can also be used in the automotive industry, that is, through vehicle radar to prevent car crashes.

Traffic guardrail is a kind of traffic safety facility set on the outside of shoulder, traffic separation zone and sidewalk kerb. The collision energy is absorbed by self-deformation or vehicle climbing, so as to change the driving direction of the vehicle, prevent the vehicle from going out of the road or entering the opposite lane, and minimize the injury to the occupants.
