Jiwei Network report The convening of the Winter Olympics has once again allowed the public to see the deep integration of sports and technology.
Known as the "Ice Ribbon", the National Speed Skating Hall is the iconic venue in the main beijing area of the 2022 Beijing Winter Olympics, and the only new ice competition venue, which will be used for the competition and training of speed skating events. In fact, speed skating not only requires the absolute speed of the athletes, but also "game skills" such as cornering techniques, transcendence techniques, following tactics, teammate cover, reasonable blocking, etc., which are also key factors that determine success or failure.
Therefore, in order to better monitor, record, analyze the athlete's gliding trajectory, and provide data guidance, the blessing of "black technology" such as positioning systems is particularly important. The core technology behind this is inseparable from the CBG9326 driver amplifier product developed by the core Baxter.
Core Baxter CBG9326: For the Winter Olympics high-precision positioning help
In this Winter Olympics, based on the UWB-AOA positioning product launched by the core Baxter CBG9326, a specific number of positioning base stations are deployed in the National Speed Skating Hall, so as to achieve centimeter-level high-precision positioning of athletes in the pavilion, monitor and record the gliding trajectory of athletes in real time, and support historical data query for more than two years. Compared with the traditional UWB positioning equipment, UWB-AOA can save nearly 80% of the cost while maintaining high-precision positioning in the same environment, which is the best response and practice of "Green Olympic" technology and energy saving.
UWB has high positioning accuracy, ultra-low power consumption, strong anti-interference, large capacity and high safety and other technical characteristics, is other traditional positioning technology does not have or do not do ideally, so UWB can quickly find its own development space in the indoor precision positioning market. UWB technology shines in this Winter Olympics, which not only enriches the market space of UWB in the field of sports, but also will promote the rapid development of UWB technology applications in other industries. As the domestic leader of RF front-end chips, Core Baxter has long laid out UWB technology and market, and has developed and mass-produced a series of RF front-end chips suitable for UWB base station positioning at the beginning of the company's establishment, and has worked with partners to deepen the market application of UWB. The successful application of their chips to the Beijing Winter Olympics this time is the result of the company's long-term unremitting efforts.
In fact, the key RF solution included in the product, the CBG9326 driver amplifier, has a lot of success inside. It is understood that CBG9326 is a high-efficiency GaAs HBT MMIC driver amplifier running at an operating frequency of 3.0-4.5GHz, and the application scenarios cover base stations, labels, children's bracelets and other fields. Capable of providing 25dBm of saturated power and 21dB of gain from a 5V supply, as well as more than 40% PAE efficiency. Available in an EMSOP8 package, packaged in a low-cost, 8-lead surface-mount housing with an exposed bottom to improve RF and thermal performance.
The amplifier is capable of providing 19dB of gain and +25dbm of saturated power at +3.3V supply voltages and 23dB of gain and +26dBm of saturated power at +5V supply voltages. When the amplifier is not in use, the power can be reduced to save current consumption. Internal circuit matching is optimized to provide more than 40% PAE efficiency.
In addition, cbG9326 related matches also include CBS8348 and CBG9092 products.
Among them, CBS8348 is a wideband GaAs pHEMT monolithic integrated single-pole double-throw switch, using lead -free 2mm-8 pin PDFN package, 0.5mm gate length GaAs pHEMT process preparation, with performance and reliability of the completely passivated process characteristics. Designed for low insertion loss, these SPDT switches maintain low losses up to 10 GHz. Typical applications are WLANIEEE 802.11a+ blg and MIMO, and other applications include test equipment that requires ultra-fast switching speeds, specifically in fiber optics, microwave radio, military, space, and small satellite ground stations.
The CBG9092 is a flat gain, high linearity, ultralow noise amplifier in a 2x2mm surface mount package of the RoHS Green Standard for base stations. In a single 3.3V-5V supply, as well as in a 68mA bias setting, 2.5GHz typically provides 22dB of gain, +37dBm OIP3, and 0.5dB noise figure.
The product integrates a disable bias function that allows the operation of TDD applications. Because the device is internally matched using a high-performance E-pHEMT process, only five external components need to be connected from a single positive power supply: an external RF choke and blocking/branch capacitors and bias resistors. The CBG9092 covers the 500–4200MHz frequency band and can reach as low as 150MHz. It is mainly used in repeater/DAS, mobile infrastructure, general wireless, LTE/WCDMA/CDMA/GSM, TDD or FDD systems.
The Era of Internet of Everything: UWB Technology Market Dividend Highlights
The advent of the era of the Internet of Everything has narrowed the distance between people, people and things, and things and things. Market research shows that more than half of future IoT applications will need to operate based on geolocation information. At the same time, with the continuous upgrading and change of the consumer market, the requirements of users and the industry for positioning accuracy have become more and more demanding.
Because of this, under the premise of the gradual maturity of the industrial chain and technical support, the outbreak of UWB technology, which is known as one of the "three musketeers of indoor positioning" in the industry, is logical. According to market research agencies Markets and Markets, the global indoor positioning market size will grow from $7.11 billion in 2017 to $40.99 billion in 2022, and will maintain a compound growth rate of 42%.
UWB technology, also known as ultra-wideband technology, is a low-power wireless communication and sensing technology that uses a narrow pulse of non-sine waves in the nanosecond range with an extremely wide spectrum to communicate. It has the advantages of insensitivity to channel fading, low transmission signal power spectral density, low interception rate, low system complexity, and positioning accuracy of several centimeters.
Different from the common continuous carrier broadband communication method, UWB uses nanosecond (0.3ns) of narrow pulse transmission data, has a more accurate positioning and perception ability, positioning accuracy up to 10cm, and can detect the angle error of movement controlled within 3 degrees, higher than WiFi, Bluetooth and other technologies of multiple orders of magnitude, and the signal anti-interference ability is strong, can carry out a large number of information transmission, can be used in wireless personal area networks, home network connection, accurate positioning and short-distance radar and other fields.
Considerable market demand has also driven the continuous increase in the layout of industrial chain manufacturers. From the current market pattern of UWB technology, the downstream application market dividend is becoming increasingly prominent, which is expected to accelerate the process of large-scale commercial use of UWB. Industry insiders pointed out: "Based on the AoA addition of UWB positioning system does not need to lay additional base stations, thanks to the ultra-wideband and narrow pulse characteristics of UWB, it is difficult to be intercepted in space, especially indoor or relatively closed, small-scale space, UWB positioning system has unique advantages over WiFi, Bluetooth, infrared, ultra-broadband and other mainstream wireless technologies, so it is very suitable for application in consumer applications." ”
Overall, with the increasing demand for precise positioning of the Internet of Things, UWB technology is bound to shine in IoT applications such as consumer markets and enterprise-level scenarios, and more innovative applications will burst out in the future. The company that has completed the development of UWB RF solutions will also actively respond to the call of new infrastructure and is committed to serving the digital intelligent economy with unique technical expertise, thus spawning a greater market dividend.
