Analog Devices, Inc. (ADI), a leading global provider of high-performance signal processing solutions, recently launched the award-winning RadioVerse technology and the latest member of the design ecosystem to simplify and accelerate wireless development for wireless operators and telecommunications equipment manufacturers, enabling their honeycomb base stations to transition from 4G to 5G networks. ADI’s expanded RadioVerse product series includes new radio transceiver hardware, software tools, and a robust design environment, helping to achieve smaller and lower power consumption radios required for next-generation networks. New products support customers to quickly evaluate and develop the radio design for 4G small honeycomb and Pre-5G massive MIMO system (the key building module for the transition to 5G), improve the data rate, and improve their connectivity and data transmission capacity in office buildings, stadiums, public transport systems and other densely populated high traffic areas.
RadioVerse addresses radio design issues at the circuit, architecture, system, and software levels. The products released this time include the AD9375 RF transceiver, which is the latest member of ADI’s highly integrated broadband RF transceiver series. The AD9375 is the first RF transceiver with built-in integrated digital pre distortion (DPD) algorithm – a design breakthrough that reduces DPD power consumption by 90% compared to rival solutions.
Due to the division of the DPD system from FPGA to transceivers, the number of channels on the JESD204B serial data interface has been reduced by half, resulting in a significant reduction in system power consumption, especially in the application scenario of Pre-5G Massive MIMO with high radio channel density requirements (the number of antennas has increased from 2 to 128 days), which brings a significant reduction in power consumption. Other advantages include a more compact radio circuit layout, which can simplify wiring and system design, reduce base station size, and allow designers to use lower cost and complexity FPGAs. In a small base station system, utilizing these advantages can enable each device to support more frequency bands, thereby increasing network capacity while minimizing the impact on system power consumption and size.
The AD9375 transceiver can be used in common radio platform designs, achieving a RF frequency range of 300 MHz to 6 GHz. The JESD204B interface supports up to 6 Gbps and has a power consumption of less than 5 W. Similar to the award-winning AD9371, the AD9375 has two built-in 100 MHz receivers, two 250 MHz transmitters, a dual channel input observation receiver, and a three channel input sniffer receiver. The integrated DPD solution of this transceiver supports 3G and 4G signals, with a transient signal bandwidth of up to 40 MHz.
In addition to the AD9375, the RadioVerse transceiver hardware combination also includes broadband components suitable for large base stations (macrocells) to picocells, femto cell base station architectures, as well as ultra-low power narrowband transceivers suitable for IoT applications that require long-distance, network robustness, and long battery life.
RadioVerse Design and Technology Ecosystem Accelerates Wireless Development
The RadioVerse technology and design ecosystem aim to assist customers in reducing radio size, weight, and power consumption (SWaP) while maintaining the highest possible radio performance. This ecosystem includes a new small honeycomb radio reference design that utilizes the complete JESD204B to antenna radio signal chain supported by AD9375. This helps customers further simplify design, accelerate product launch, and minimize engineering costs. This reference design was developed in collaboration with wireless solution provider Benetel Ltd and supports 2×2 20 MHz LTE with an output power of 250 mW per antenna. The overall system power consumption is less than 10 W, and the overall size is very small (88 mm x 83 mm).
Does the ADI RadioVerse tabletop development platform also support the use of MATLAB? And Simulink? Modeling software performs advanced simulation and analysis of transceivers, providing device drivers and a complete evaluation system that can be directly connected to FPGA development platforms, as well as third-party hardware, enabling customers to quickly turn concepts into products for market launch. In the design environment, customers can visit ADI EngineerZone? Online technical support forums to accelerate the product launch process, including customer support forums, quick start videos, technical articles, online seminars, and product focus.
ADI will continue to expand the RadioVerse design environment through alliances with leading power amplifier (PA) suppliers such as NXP Semiconductor N.V. and Skyworks Solutions, Inc., and provide customers with test reports on the use of AD9375 DPD with PA products of different output powers and frequencies. Welcome to the RadioVerse Alliance website, which has rapidly expanded to 20 companies in the past 12 months and includes 7 new reference designs for the drone, wireless surveillance, and software defined radio markets.
