Josun Micro is a manufacturer of LNAs, PAs, RF switches, RF filters, and RF front-end modules, and has been a leader in the domestic RF front-end field, which is now widely used in cell phones, communication base stations, automotive electronics, drones, and Bluetooth headsets. This time, Huawei also purchased most of the RF front-end devices from Josun Micro. At present, although Josun Microsystems has done a very mature job in SAW low and medium frequency filters, there is a big gap between Josun Microsystems and mainstream filter manufacturers in BAW high frequency filters. Josun Micro in the BAW filter this piece also through the capital market, to increase investment, but also hope that Josun Micro as soon as possible to break the technical bottleneck.
Shengbang Microelectronics is a focus on analog chip R & D enterprises, mainly the production of high-performance analog chips, is currently the main coverage of the signal chain and power management of the two major areas, has become the leading domestic analog device enterprises.

Although Sanborn Micro in the analog devices on a wide range of layout, currently in the operational amplifiers, power supply chips and other devices to occupy a very large market share, but also made great technological breakthroughs, but in the design, process and production is still with Texas Instruments, Qualcomm, ADI and other companies there is a big gap, I believe that with the development of time, with the accumulation of technology, sustained investment, the improvement of production process
We have been working on the development of our own analog chips for a long time, and we have been working on the development of our own analog chips.
Weir's main products are divided into: 1, analog chips: power supply chips, RF chips and signal chain products; 2, CMOS image sensing: mainly used in cell phones, automobiles, security, three major camera applications. Weir shares since the merger and acquisition of Howell Technology and Spectrum, the core business has changed from analog chip business to CMOS sensor business, the main competitiveness of the CMOS image sensing field, CIS chip direction tilt, the current piece of business has also been done in the world's top three.
Weir shares in April 20 spent 120 million U.S. dollars to acquire Synaptics TDDI (display touch driver integration business) business, Weir shares in the field of display touch control has a place. synaptics can rely on Weir shares of domestic customer resources, vigorously promote the TDDI technology, is expected to achieve rapid growth.
Weir is the only listed company in the A-share market to realize the full layout of pan-analog chips, and currently occupies an important position in the field of analog circuits and radio frequency. In TVS products, USB switches, mems and other product areas have come to the forefront of the domestic, the company is currently increasing the layout of the RF field, plans to do 5G switch, PA, SAW products.
The top of the convergence of science and technology (603160.SH) is a chip design and software development based on the overall application of the solution provider, is now mainly for the intelligent terminal, Internet of Things and automotive electronics to provide leading semiconductor hardware and software solutions. The products and solutions have been widely used in Huawei, OPPO, vivo, millet, Samsung, Google, Amazon, Dell, HP, LG, a plus, Nokia, ASUS and other international and domestic brands, serving hundreds of millions of people around the world, is to drive all things connected to the leading provider of IC design and solutions.
At present, it has extensively laid out low-power Bluetooth, health sensors, audio amplifiers, microcontrollers, biometrics products and human-computer interaction products, but the main revenue comes from biometrics products, and other products still need to continue to make efforts.
Mainly engaged in the design, research and development, manufacturing and sales of camera modules, is the world's third largest smartphone camera module packaging and testing enterprises. Based on the expertise accumulated in the camera module packaging and testing industry over the past 14 years, the company is one of the few companies in China that is the first to adopt chip-on-board (COB), film-on-film (COF), mold-on-board (MOB) and mold-on-chip (MOC) technologies in camera module manufacturing and is capable of mass production and sales of ultra-thin camera and dual/multi-camera modules ranging from 2 to 108 million pixels. It is also the first one to mass produce 3D structured light module and the first one to mass produce micro gantry module in China.
In recent years, the company has continued to make efforts in the field of high-end cameras, and has launched innovative camera modules, including optical stabilization (OIS) camera modules, 3D Sensing camera modules, automotive camera modules, drone camera modules, smart home camera modules, etc. However, the current coverage of the industry is still relatively homogeneous. However, the current product coverage of the industry is still relatively single, subject to market influence is relatively large, and the dependence of large customers is also relatively strong.
