At the 68th International Solid-State Circuits Conference held on Wednesday, China Electronics Technology 38 released a high-performance 77GHz millimeter wave chip and module that achieved two three-round chips for the first time in the world. 4 Receive millimeter wave chip and 10-millimeter wave antenna single package integration.
This high-performance 77GHz millimeter wave chip and module have a detection distance of 38.5m, setting a new record for the longest detection gap of a millimeter-wave package antenna in the world.
According to the official, the packaged antenna module released this time contains two self-developed 77GHz millimeter-wave radar chips, using low-cost CMOS technology, monolithic integration of 3 transmitting channels, 4 getting channels, and radar waveform generation, etc.
The main performance indicators have reached the international advanced level to meet the demand for core millimeter-wave sensors in the field of intelligent driving.
This 77GHz millimeter-wave chip has an area of 24mm×24mm, but in this small space, it has realized the function of multi-channel millimeter-wave radar transceiver front-end, creatively proposed a dynamically adjustable fast broadband chirp signal generation method, and Multi-feed antenna technology is used in the package.
In addition, the 38th China Electric Power Research Institute also declared that it will further optimize the millimeter-wave radar chip and change it according to the expansion of application requirements and technological progress, and give one-stop solutions according to specific application scenarios.
