STMicroelectronics (ST) released a new wireless front-end technology platform for wireless products. The optimized silicon-on-insulator (SOI) process significantly reduces the size of 4G and other wireless high-speed communication multi-frequency RF chips. The new process H9SOI_FEM can manufacture modules that integrate all RF front-end functions.
Flavio BenetTI, general manager of mixed-signal process product department of STMicroelectronics, said: "H9SOI_FEM special process allows customers to develop the most advanced front-end modules whose size is only one-half or less of the current front-end solutions. In addition, we have developed The simplified supply process can significantly shorten the supply cycle and increase supply flexibility, which is critical for end users in the market. "
ST is currently working with customers to develop new designs using H9SOI_FEM. It is expected to enter the mass production preparation stage by the end of this year.
Interpretation:
With the rapid growth of consumer demand for high-speed wireless broadband networks, the current annual sales of smart phones exceed 1 billion units, a growth rate of about 30%. Mobile products such as smartphones and tablets require more complex radio frequency circuits. In order to meet this market demand, it is necessary to improve the performance of the RF front-end of mobile devices. Due to the size limitations of portable devices and more and more integrated things, how to reduce the circuit size and integrate complex functions also needs to be considered. Smaller, thinner, and more energy efficient devices will be the future choice.
In addition, as new high-speed connection standards such as 4G mobile communication and Wi-Fi (IEEE 802.11ac) begin to use multi-frequency technology to improve data throughput, the latest mobile devices need to increase the front-end circuit, which will cause the front-end template size to become larger. ST's new process H9SOI_FEM is an evolution of the H9SOI silicon-on-insulator process. It can manufacture modules that integrate all RF front-end functions, such as RF modules with integrated power amplifiers and switches and modules with integrated power amplifiers, switches and tuners. Smaller size and more functions will be a big selling point.
The number of smart cities is expected to exceed 600 at the end of the 12th Five-Year Plan
According to the news at the "China Smart Building Summit" recently, 90 cities, districts and towns have become the first batch of national smart city pilots. During the 12th Five-Year Plan period, it is expected that 600 to 800 cities in China will become smart cities.
Interpretation:
The development of smart cities in China has entered the stage of scale promotion. Up to now, 154 cities in China have proposed to build smart cities. The total investment is expected to reach 1.1 trillion yuan, and the investment will be in trillions of dollars. A new round of industrial opportunities is coming. Related wireless sensors, mobile internet, intelligent transportation, Internet of Things, etc. will step into the fast lane.
TI pushes the industry's smallest low-power dual-channel button reset controller
A few days ago, Texas Instruments (TI) announced the launch of two miniature button reset controllers for low-power applications with limited space such as pedometers, fitness bands, cell phones, and tablets. The dual-channel TPS3420 and TPS3421 have low power consumption and an optional reset time delay to enhance system stability.
TPS3420 and TPS3421 use long time input delay, not only can provide the required system reset, but also can avoid short time button or key press to generate reset. This reset configuration can differentiate between software interrupts and hard system resets. These timers are the first products of TI's latest button controller series, which can ensure a full hard reset of the system when efficiency is needed.
Interpretation:
Portable devices are a big blue ocean, and batteries are a major bottleneck for portable devices. Low power consumption is an important measurement criterion for portable devices. TI introduced the industry's smallest low-power dual-channel button reset controller for portable applications Miniature package, 1.45 mm × 1.0 mm × 0.55 mm small SON package, which takes 70% less board space than competing devices. The low quiescent current of 250nA can save power for portable electronic products. These advantages will enhance product competitiveness.
Asia Mobile Expo opens on the 26th
On the morning of June 26, the 2013 Asian Mobile Communications Expo hosted by the GSM Association opened today at the Shanghai New International Expo Center. With the theme of "Connection The Future", this expo attracted many exhibitors from China and all over the world. China Telecom, China Mobile, China Unicom and Huawei and other Chinese communications leaders made a wonderful appearance.
Interpretation:
Mobile payment and connected life will be the highlight of this time. In addition, China Mobile recently started bidding for 4G, and the 4G concept may start to lead the mobile communications. 3G is not yet mature, 4G has risen, 5G is on the move, where is the future of mobile communications? How can we link the future? Technology is running so fast that many people feel they can't keep up!
A new generation of iPhone will be available on September 27
According to foreign currenteditorials media reports, Apple will hold a new product launch event on September 18 this year to officially release the next generation of iPhone smart phones, and the new generation of iPhone will be officially listed for sale on September 27. It is reported that the appearance of the new generation iPhone is similar to the current iPhone 5, but it will have a new processor and a larger capacity battery.
Interpretation:
Will the new generation of iPhone continue to write about the myth of Jobs, and will be overshadowed by the rivals of Samsung and other rivals? Will consumers treat the new generation of iPhones with the same craziness they had before? Everything remains to be tested by time.
ZTE's industry's first to achieve 1Gbps cross-band carrier aggregation
On June 26, 2013, at ZTE ’s MAE (Asian Mobile Communications Expo) held in Shanghai, the industry ’s first live demonstration of F + D cross-band 4 carrier carrier aggregation (CA) demonstrated a rate of 1Gbps. This demonstration uses 4 carriers to implement cross-band carrier aggregation, of which 3 carriers work in the 2.6G band and 1 carrier works in the 1.9G band. This is another technological leap after ZTE successfully demonstrated F + D cross-band carrier aggregation to reach a peak rate of 430Mbps in Beijing in February.
Carrier aggregation is the core technology of LTE-A. It can combine two or more carriers in the same or different frequency bands into a single channel to increase the peak rate of TD-LTE cells by a factor of two. At the same time, the technology can also effectively avoid co-channel interference in neighboring cells, improve TD-LTE network performance, more flexibly achieve load balancing between primary and secondary cells, and increase network capacity. The application of carrier aggregation technology can enable operators to provide mobile users with a higher speed and richer service experience, better cope with the explosive growth of data service traffic, and improve the competitiveness of TD-LTE networks.
Interpretation:
Recently, China Mobile started bidding for 4G, and this demonstration will boost 4G. 2013 is the first year of TD-LTE large-scale network construction. The TD-SCDMA network resources can be used to quickly upgrade the TD-LTE network in the F-band, but the F-band has only one 20MHz frequency point. To achieve capacity expansion to meet mid- to long-term business development needs, it can also double the TD-LTE network carrying capacity, enhance load balancing between different frequency points, and improve network performance. Realizing F + D cross-band 80MHz carrier aggregation is a strategic technological breakthrough. This demonstration of the 4-carrier F + D cross-band carrier aggregation function further embodies ZTE ’s leading strength in TD-LTE, and more importantly, for China Mobile ’s subsequent large-scale F + D joint networking and frequency resource integration And effective use provides strong technical support and basis.
