ADI targets RadioVerse technology for 4G to 5G, and massive-MIMO

ADI targets RadioVerse technology for 4G to 5G, and massive-MIMO

New Products |
By Graham Prophet



ADI’s expanded RadioVerse portfolio features new radio transceiver hardware, software tools, and a design environment to support the smaller, lower power radios necessary in next generation networks. The new offering allows customers to quickly evaluate and develop radio designs for 4G small cell and Pre-5G massive MIMO systems, key building blocks in the transition to 5G.

 

The AD9375 RF transceiver absorbs the digital pre-distortion (DPD) function into the single-chip; the complete closed-loop signal quality control is hosted, saving complexity and power. ADI estimates that power expended on DPD may be reduced by as much as 90%.

 

There will still be an FPGA in basestation designs, AD says, but it will be smaller and less power-hungry, not least by elimination of multiple JESD204B serial data interface lanes. The AD9375 transceiver enables a common radio platform design that is tunable over a range of 300 MHz to 6 GHz, operates on a 6-Gbps JESD204B interface and consumes less than 5 Watts. Similar to the AD9371, the AD9375 has two 100-MHz receivers, two 250-MHz transmitters, a two-input observation receiver (sampling the output to close the DPD loop) and a three-input sniffer receiver. The transceiver’s integrated DPD solution supports 3G and 4G waveforms with an instantaneous signal bandwidth of up to 40 MHz.

 

The RadioVerse technology and design ecosystem includes a new small-cell radio reference design with a full AD9375-enabled JESD204B-to-antenna radio signal chain. This helps engineers further simplify design and accelerate time to market, while minimizing engineering costs. Developed in partnership with Benetel Ltd., a radio solutions provider, the reference design supports 2×2 20-MHz LTE with 250-mW output-power-per-antenna and consumes less than 10 Watts, all in a small form factor measuring 88 mm 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 full evaluation systems that directly connect to FPGA development platforms, and third-party hardware.

 

Analog Devices will continue to expand its RadioVerse design environment through partnerships with leading power amplifier (PA) suppliers, including NXP Semiconductors N.V., and Skyworks Solutions, Inc., providing customers with test reports for AD9375 DPD with PA products of various output power and frequencies.

 

In a 12 x 12 BGA the 9375 costs $325 (1000); the eval kit is $1450 and the small-cell reference design, $2995.
