The ADI millimeter wave 5G chipset supports the full 5G NR FR2 spectrum for a simpler, smaller radio solution
Beijing, China -- Analog Devices,Inc. has introduced a millimeter wave (mmW)5G front-end chipset capable of meeting the required spectrum requirements, enabling designers to reduce complexity and bring smaller, general-purpose radios to market faster.Consisting of four highly integrated ics, the chipset provides a complete solution that significantly reduces the number of devices required for 24GHz to 47GHz 5G radio applications.
As the global deployment of MILLImeter-wave 5G accelerates, operators are under greater pressure to both reduce rollout costs and expand network coverage with more energy-efficient, lighter and more reliable radio products.This requires highly linear, compact, and energy-efficient broadband products that allow reuse of multi-band designs without sacrificing quality and performance.ADI's millimeter-wave 5G front-end chipset has enabled Original equipment manufacturers (Oems) to move away from narrowband mode.In the narrowband model, competitive solutions trade improved design execution difficulty and reduced radio frequency (RF) performance for bandwidth, while outsourcing key intellectual property such as packaging, testing and thermal modeling.
The new chipset includes two single-channel (1T1R) up/down converters (UDCS) and two dual-polarized 16-channel beamforming devices using advanced CMOS technology.Compared to other solutions, the power efficiency and linear output power provided by this beamshaper enable the size, weight, power and cost of millimeter wave phased array designs to be reduced.The all-frequency up/down converter has a high drive level, which eliminates the need to provide multiple models in different frequency bands, and combines drive stages to save material costs.In addition to factory-configured non-volatile memory (NVM) via patented IP, the chipset also enables seamless on-site, online operation of phased array calibration capabilities.This enables Oems to break out of the traditional design constraints of only NVM architectures, which are limited to one-time factory calibration of beamformers.This calibration will not solve the problem of non-ideal characteristics outside the IC and will result in sub-optimal calibration results.
ADI's MILLIMETER wave 5G front-end chipset includes:
