A millimeter-sized chip
seemingly insignificant
But it's all about "power."
Located in Jiangbei New District Research Park, Nanjing Star Semiconductor Co., Ltd., self-developed satellite baseband chip CS7620 in recent days successfully lit, and completed the first pass of high-definition video call test.End-to-end validation of a direct cellular satellite connection solution was achieved.
"This is the company in
A major breakthrough in the field of direct satellite connectivity for cellular phones.
We are also the only one in the country to have
Bringing Chip-Scale Solutions
Teams linking with low-orbit broadband satellites.
Combining terrestrial, celestial, and space communications signals
Interconnections.
Let everyone even on the airplane,
You can get online in the middle of the ocean."
This also marks a further step in the commercialization of the company's chip landing," said Xu Xin, head of research and development at Star Semiconductor.Next year, everyone will be able to see terminal devices using this chip on the market."
In the past, satellite phone charges were high and the scope of use was narrow, making it very remote from ordinary users. With the continuous upgrading of cell phone functions, nowadays, satellite communication has almost become one of the "entry thresholds" of high-end smart phones. At the beginning of this year, the Ministry of Industry and Information Technology and other seven departments jointly issued "on the promotion of future industrial innovation and development of the implementation of the views", mentioning the strengthening of forward-looking planning and deployment of future information, and promote the industrialization of satellite Internet applications.
It is understood that the satellite Internet is based on satellite communications technology to access the Internet, as if the ground base station moved to space, each satellite is a mobile base station.
"The initial satellite call is somewhat similar to the feeling of the 2G era, and then appeared Beidou short message, is similar to the form of SMS, MMS to carry text and pictures, we this time the use of low-orbit broadband satellite technology, upstream and downstream rate of more than 100Mbps, you can use the traffic to surf the Internet, transmission of high-definition pictures, and even video calls," he said.The basis for these features to be realized is that we have made significant improvements in both the operating bandwidth and the transmission rate of the chip."Xu Xin said.
Calling, tweeting, swiping videos ......
When we use our cell phones
Baseband chips responsible for communication functions
It's playing a big role.
It is worth noting that, originating from the company's evolution in 5G communication technology, in addition to satellite communications, the satellite baseband chip can also be accessed with LTE base stations and 5G base stations on the ground, theIt supports a variety of terminal forms and application scenarios such as direct satellite connection for cell phones, satellite broadband access, satellite Internet of Things, industrial interconnection, wearable watches, feature phones, and so on.
To advance the commercialization of new products on the ground
Star Semiconductor has a new schedule.

"Currently, we are working with industry-leading handset manufacturers, satellite terminal manufacturers, module manufacturers, and MBB (mobile broadband) vendors, among others, and plan to launch terminal products based on the CS7620 chip in 2025. The next critical task is the technical coordination of the satellite in the sky. We have already arranged for staff to go for the final intermodulation work before the satellite launch." Xu Xin said that the next step is that he will also lead the team to carry out the relevant certification of the national laboratory as well as operator certification for this chip, get the network license, and accelerate the realization of commercial applications.
