Analog Devices updates RadioVerse technology for 5G transition
Analog Devices (ADI) has updates its RadioVerse technology and design ecosystem, adding new radio transceiver hardware. Together with software tools and a robust design environment, RadioVerse technology enables the smaller, lower power radios necessary in next generation networks which simplifies and accelerates radio development for wireless carriers and telecommunications equipment manufacturers as they transition their cellular base stations from 4G to 5G networks.
ADI’s expanded RadioVerse portfolio’s new offering allows customers to quickly evaluate and develop radio designs for 4G small cell and Pre-5G massive multiple input, multiple output (MIMO) systems. These are key building blocks in the transition to 5G, says ADI, enabling faster data rates while improving connectivity and data throughput in densely populated, high-traffic areas such as office buildings, sport stadiums and public transit systems.
Addressing radio design at the circuit, architecture, system and software levels, the updated RadioVerse release includes the AD9375 RF transceiver, the newest addition to ADI’s integrated wideband radio frequency (RF) transceiver series. The AD9375 is the first RF transceiver to incorporate the digital pre-distortion (DPD) algorithm on-chip. This design breakthrough reduces DPD power consumption by 90 per cent compared to competing solutions, says ADI.
The re-partitioning of the DPD system from the field programmable gate array (FPGA) to the transceiver halves the number of JESD204B serial data interface lanes. This results in dramatic power savings, particularly as the number of antennae per basestation increases from two to 128, in support of Pre-5G massive MIMO radio-channel density requirements. Other benefits include a more compact radio circuit layout, which simplifies routing and system design, reduces basestation size, and allows designers to use a lower-cost, less complex FGPA. In small cells these benefits allow more frequency bands per cell for increased network capacity, while minimising the impact to system power consumption and size.
The AD9375 transceiver enables a common radio platform design that is tunable over a range of 300MHz to 6.0GHz, operates on a 6.0Gbit/s JESD204B interface and consumes less than 5.0W. Similar to ADI’s AD9371 model, the AD9375 has two 100MHz receivers, two 250MHz transmitters, a two-input observation receiver and a three-input sniffer receiver. The transceiver’s integrated DPD supports 3G and 4G waveforms with an instantaneous signal bandwidth of up to 40MHz.
In addition to the AD9375, the RadioVerse transceiver hardware portfolio features wideband devices for basestation architectures, ranging from macro- to pico- and femto-cell form factors, in addition to low power, narrowband transceivers for industrial internet of things (IIoT) applications that require long range, network robustness, and long battery life.
Developed to help customers reduce radio size, weight and power (SWaP) while maintaining radio performance, the RadioVerse technology and design ecosystem includes a new small-cell radio reference design with an AD9375-enabled JESD204B-to-antenna radio signal chain. This helps customers simplify design and accelerate time to market, while minimising engineering costs, says ADI. The reference design was developed in partnership with Benetel, and supports 2×2 20MHz long term evolution (LTE) with 250mW output per antenna and consumes less than 10W. This is all integrated into a small form factor measuring 88 x 83 mm.
ADI’s RadioVerse prototyping platforms also provide advanced simulation and analysis of the transceiver using MatLab and Simulink modelling software, device drivers and evaluation systems that directly connect to FPGA development platforms, and third-party hardware. The design environment accelerates customer time-to-market through access to EngineerZone, ADI’s online technical support community, which hosts customer support forums, quick-start videos, technical articles, webcasts and product highlights.
Analog Devices will continue to expand its RadioVerse design environment through partnerships with leading power amplifier suppliers, including NXP Semiconductors and Skyworks Solutions, providing customers with test reports for AD9375 DPD with power amplifier products of various output power and frequencies.
