Because in the global joint rescue of the Thai youth football team, Israel's Maxtech Networks company provided 17 communication equipment to play a key communication guarantee. The software radio using frequency agile technology is used in the harsh environment of non-line-of-sight range such as the water cave in the flood season. A vital communication network was built to realize real-time communication between rescue team members outside the cave and the trapped. These key communication devices use a highly integrated RF frequency agile transceiver AD9364 under the RadioVerseTM brand of ADI. The low power consumption, high performance, and broadband frequency agility characteristics make it a hero behind the scenes. In fact, as a development environment platform that aims to solve the problems of software-defined radio technology and provide broadband transceivers and a combination of software and hardware to the market, the series of broadband RF transceivers of the RadioVerse ecological platform are used in many wireless communications across industries and applications. Widely used, such as unmanned aerial vehicles, cellular base stations, relay backhaul, and even handheld spectrum analyzers and other products. At the recent ADIRadioVerse new product launch conference, ADIRadioVerse marketing manager Weng Jie introduced ADIRadioVerse's latest generation of broadband transceivers-ADRV9008/9, the industry's highest bandwidth RF transceiver. The RadioVerse technology platform has launched invincible new products for the first time in a year, demonstrating the technical strength of its wireless technology leader. ADI RadioVerse marketing manager Weng Jie introduces a new generation of transceiver products As we all know, 5G technology is very different from 4G, including air interface, coding, baseband, etc. The most direct challenge is to expand the spectrum and expand the bandwidth. In the past, the 2G/3G/4G spectrum was generally concentrated below 2GHz and 2.7GHz, while the 5G spectrum has included 3.5GHz, 4.9GHz, etc., and millimeter wave frequency bands will be used in the future. For a long time in the future, 2G/3G/4G will coexist with 5G networks. Therefore, telecommunications equipment manufacturers need new RF front-end products to cover all new and old frequency bands. This poses a major challenge for operators and communication equipment providers-how to provide 5G services to some customers while still satisfying the 2G, 3G and 4G needs of other customers? The launch of ADRV9008/9 is in response to such objective market requirements. The industry’s first RF transceiver that supports all existing cellular standards can be tuned from 75 MHz to 6 GHz and supports 2G/3G/4G/5G services. , So cellular equipment manufacturers can use a single compact radio design to meet all frequency bands and power requirements. Mobile Expert's base station shipment forecast for February 2018 The unique performance advantages enable the ADRV9009 to support narrowband applications, ultra-wide bandwidth, open up the versatility to realize 5G, support multi-carrier GSM and narrowband Internet of Things, and 3GPP standards. At the same time, because the single-chip solution can replace more than 20 discrete devices, it greatly reduces SWaP and design complexity, and shortens the time to market. In this way, operators can use massive MIMO to achieve network density. As a product for 5G applications, ADRV9009 simplifies digital beamforming design by processing local oscillator (LO) synchronization on-chip is also an important feature. The beamforming technology is mainly used in 5G Massive MIMO and phased array radar. Massive MIMO has up to 64x64 or even 128×128 antenna channels. Because ADRV9009 can support the phase synchronization of internal local oscillators, external local oscillators and external discrete components are not needed, which simplifies multi-chip phase calibration and greatly reduces the system The complexity and cost and power consumption. In order to accelerate the time to market for customers using ADRV9009 RF transceivers, the current RadioVerse ecosystem will provide a JESD204B FPGA system module (a production-ready RF system module with 4 ADRV9009 devices, 8 receivers, 8 issuances and FPGAs) by the end of 2018, and Provide customers with additional design and technical services through a global partner network. In addition, Weng Jie described the industry application cases of ADRV9008/9 from the following three main application scenarios, and shared the latest layout of the ADI RadioVerse product line. In addition to the 2G/3G/4G/5G basic communication network described above, the RF performance advantages of ADRV9009 are also applicable to communication infrastructures such as cellular base stations and Massive MIMO. In the field of communications, Weng Jie introduced the single-chip TDD solution of ADIRadioVerse ADRV9009 and the dual-chip FDD solution of ADRV9008-1/-2. Among them, the single-chip TDD solution shares a LO local oscillator between Rx and Tx, and runs at 50% Rx/Tx duty cycle in TDD mode. The integration is high, and the single-chip power consumption can be controlled within 5W. The dual-chip FDD solution splits Rx and Tx. 9008-1 is a dual-receiver solution, while 9008-2 is a dual-transmitter plus loopback channel design. The single-chip TDD solution of ADRV9009 and the dual-chip FDD solution of ADRV9008-1/-2 are perfectly complementary In the rescue of the Thai youth football team, Maxtech Networks' equipment makes good use of the frequency agility characteristics of AD9364, continuously analyzes the spectrum existing in the environment and automatically adjusts the frequency. They automatically adjust the frequency and establish stable communication with the nearest network node to successfully avoid it. Overwhelmed by environmental wireless noise. It is not surprising that AD9364 plays a key role in it. ADI’s RadioVerse technology platform has set emergency communications in several major target applications including 4G and 5G from the very beginning. Emergency communications require radio communications that are light in weight, rugged and durable, have high power efficiency, can flexibly work at multiple frequencies, and are easy to use under extreme environmental conditions. This is a major challenge to traditional technical implementation solutions. With the industry's highest bandwidth and highest performance characteristics, ADRV9009 will continue to play a key core role in key communications fields including emergency communications. According to Weng Jie, the ADRV9009 combines phase-locked loop (PLL) agility and pre-calibration to achieve an unprecedented level of fast frequency hopping, which not only reduces system downtime, but also reduces the probability of communication being detected and intercepted, thereby ensuring the chain Road safety, environmental awareness and spectrum efficiency. "The key communication applications of professional drones and robots for emergency teams are the areas where ADIRadioVerse products are working hard. For example, such as high-definition wireless image transmission, the general Wi-Fi transmission distance is only a few hundred meters, and the image based on RadioVerse technology The transmission distance can reach more than 20 kilometers, and the performance is very outstanding." Weng Jie pointed out, "In addition, ADRV9009 can also be applied to phased array radar, such as weather radar to achieve weather monitoring, air quality monitoring, etc." In addition to the above two points, ADIRadioVerse products can also be used in the field of test instrumentation, such as portable communication test equipment. We know that the 5G test plan is more advanced than the 5G network deployment. The adaptability of ADRV9009 in software-defined radio SDR has also attracted the attention of test and measurement vendors. As ADRV9009 has a 200MHz receiving bandwidth, it can greatly meet the needs of test instrument manufacturers. In addition, the ADRV9009 has been fully integrated in the RF front-end and supports the modular structure of scalable SDR solutions, which can simplify the front-end architecture, reduce SWaP and cost, and provide the possibility for portable test instruments. "ADI has many customers specializing in board cards, and the board card is characterized by temporary assembly, which can ensure that the frequency can be quickly adjusted during on-site deployment, and can be adjusted to SDRs of different frequency bands according to needs. RadioVerse's transceiver products are currently in this field. It has been widely adopted.†Weng Jie revealed, “In portable test equipment, a platform that can test both mobile phones and IoT network terminals can create a very cost-effective test solution.†The RadioVerse technology and design ecosystem provides customers with integrated transceiver technology, a robust design environment and technical expertise for specific markets, making it famous for its radio design to quickly change from concept to product. The ecosystem’s transceiver technology can reduce radio size, weight, and power consumption (SWaP). The design environment provides board-level support kits, software, and tools to help customers simplify and accelerate radio development for various applications, including wireless infrastructure, Aerospace defense and electronic measurement, etc. This technology and design ecosystem provides integrated RF transceivers, software APIs, design support kits, complete documentation, ADI EngineerZone online technical support community and other resources to accelerate customer product launches and provide integrated broadband RF The transceiver evaluation board can be directly connected to the FPGA development platform to support customers to perform wafer-level performance evaluation and to quickly develop a complete radio prototype using a single hardware platform. The RadioVerse ecosystem helps realize wireless communication across industries and applications Looking back at the "timetable" of RadioVerse's product launches in recent years, from ADI's first-generation revolutionary agile transceiver AD9361, to the wider bandwidth AD9371, and last year's introduction of integrated DPD (digital predistortion) ) The functional transceiver AD9375 is constantly evolving in terms of integration, bandwidth, technology and performance. According to Weng Jie, "ADIRadioVerse will launch a blockbuster product every year to give back to the market and customers." The product continues to implement the "common platform" concept that ADI has always advocated, and is committed to covering almost all agreements with one platform. Provide efficient solutions for a wide range of applications, including communications, defense, and electronic test and measurement (ETM).
