Record breaking distance measurement for domestic 77 GHz millimeter wave chip packaged antenna

Science and Technology Daily News (Reporter Wu Changfeng): According to China Electronics Technology 38 Institute, at the 68th International Solid State Circuit Conference (ISSCC2021) held on February 17th, the institute released a high-performance 77GHz (gigahertz) millimeter wave chip and module, achieving the first international integration of two 3-transmitter and 4-receiver millimeter wave chips and 10 channel millimeter wave antennas in a single package, with a detection distance of 38.5 meters, Set a new global record for the farthest detection distance of millimeter wave packaged antennas

Science and Technology Daily News (Reporter Wu Changfeng): According to China Electronics Technology 38 Institute, at the 68th International Solid State Circuit Conference (ISSCC2021) held on February 17th, the institute released a high-performance 77GHz (gigahertz) millimeter wave chip and module, achieving the first international integration of two 3-transmitter and 4-receiver millimeter wave chips and 10 channel millimeter wave antennas in a single package, with a detection distance of 38.5 meters, Set a new global record for the farthest detection distance of millimeter wave packaged antennas.

The packaged antenna module released this time includes two 77GHz millimeter wave radar chips, which are aimed at the demand for core millimeter wave sensors in the field of intelligent driving. The chip adopts low-cost CMOS (complementary metal oxide semiconductor) technology, integrates three transmission channels, four reception channels, and radar waveform generation on a single chip. Its main performance indicators reach international advanced levels, and it has special advantages in fast broadband radar signal generation and other aspects, The chip supports multiple cascades and builds larger radar arrays. Fan out wafer level packaging is a mainstream implementation approach for packaged antennas, and major international companies have developed chip products for integrated packaged antennas based on this technology.

Next, China Electronics Technology 38 Institute will further optimize the millimeter wave radar chip and provide a one-stop solution based on specific application scenarios.

ISSCC is considered the "Olympic Games" in the field of integrated circuits, founded in 1953 by institutions such as Bell Laboratories, which invented transistors. In its more than 60 years of history, many milestone inventions in the history of integrated circuits have made their debut here.
