"The spring breeze brings joy to the horse's hooves, and I can see all the flowers in Chang'an in one day." In May, the ancient capital of Xi'an is full of spring and vigor. In the key year of comprehensively implementing the spirit of the 20th Party Congress, experts and scholars of radar industry gathered in the beautiful ancient city of Xi'an.
2024 4th Radar Future Conference was successfully held in Xi'an International Convention and Exhibition Center from 11th to 12th. 
The Radar Future Conference is an industry event initiated by the China Radar Industry Science and Technology Committee. It aims to bring together high-end experts and talents from inside and outside the radar industry to discuss strategies for integrating radar technology into various industries, discuss cross-industry collaborative innovation and development plans, and jointly promote the radar and application industry. Deepen reforms and jointly promote national defense construction and economic development.

This conference is jointly sponsored by China Radar Industry Association, China Radar Industry Science and Technology Committee and Xi'an University of Electronic Science and Technology. Through a series of "Radar and" theme sub-forum activities, the conference will jointly explore and promote the expanded application of radar and related technologies, forming a gathering force , a full-factor industry ecology that promotes production through development and makes full use of production.
Through careful organization and planning, SKE/Anhui ShengKe Microelectronics presented millimeter wave radar chips and radar level measurement products at the event held in Xi'an, China. 

The 76~81GHz highly integrated radar chip with CMOS process developed by SKE is in mass production now. The chip integrates radar transceiver front-end, MCU, coupler and AIP antenna, which is highly integrated and of low cost, making the chip widely used in economical radar level sensors and other industrial and civil fields. Our research and development of 76 ~ 81GHz and 92-96GH two gallium arsenide (GaAs) process RF transceiver front-end chip, compared with the traditional CMOS process radar transceiver chip, the transmitter power is greatly increased (12dBm to 18dBm), the noise figure is reduced (12dB to 4.5dB), so the radar front-end signal quality is greatly improved.

The gallium arsenide (GaAs) process 76~81GHz radio frequency transceiver front-end chip received great attention from the participating automotive radar OEMs at the exhibition. In recent years, domestic automotive millimeter wave radars have developed rapidly, and a number of excellent automotive radar OEMs have been produced. However, most of the OEMs are based on CMOS silicon-based millimeter wave chips. Due to poor performance, they can only be used for automotive rear angle radars. . Most of the higher value-added automotive forward radars are monopolized by large foreign brands. The mass production of this RF front-end chip from SKE hence filled the gap in domestic high-end automotive radar chips and helped domestic radar OEMs tackle high-performance automotive forward radars.
Another typical use of this chip is high-performance radar level sensor. In recent years, many excellent 80G radar level meter development solutions have emerged in China, but they are all based on CMOS silicon-based chips. Due to the low signal-to-noise ratio, they can only measure small range and simple media. High-end large-range and complex medium level measurement has been monopolized by foreign brands such as VEGA, E+H, EMERSON, and SIEMENS.
Since these brands all use gallium arsenide (GaAs) process RF chips, their products have excellent performance and can solve the problem perfectly. Industrial level measurement problems. SKE devotes great efforts to breaking this monopoly and develops China's high-performance 80G level radar. The 92-96GHz gallium arsenide (GaAs) process radio frequency transceiver front-end chip has been sought after and highly concerned by the participating traffic radar mainframe manufacturers and various research institutes, and has been given high praise. Many manufacturers even said that after all the hard work, they finally finally Found this chip.
According to the latest draft of the "Civil Radar Radio Management Regulations (Trial)" issued by the State Radio Office, [2023] No. 69), the frequency range used by traffic roadside radar is the 92GHz-93GHz frequency band. The traffic radar solutions currently used on the market all use radar in the 24GHz frequency band and 79GHz frequency band. SKE's 92-96GHz gallium arsenide (GaAs) process radio frequency transceiver front-end chip fills the gap in the frequency band of traffic radar and will surely contribute to the development of traffic radar and road-vehicle collaboration.

Respected leaders, customers, colleagues, dear friends of SKE, thank you for the long-term support and love for our company, we value the opportunity of each exhibition to meet you and to discuss the radar sensor industry's new technology and status, you are welcome to consult at any time to communicate. In the future, we will continue to concentrate on development of radar new technologies, to follow the industry's innovative new direction , and to promote the radar industry to better serve the socio-economic development.
