Smaller Size for 5G Radios
Analog Devices has released a new chipset which, it says, will enable designers of 24-47GHz 5G radios to reduce the size of their devices.
The millimetre wave 5G front-end chipset includes two single-channel up/down converters and two dual-polarisation 16-channel beamformer devices. “The power efficiency and linear output power provided by the beamformers enable size, weight, power and cost reduction in mmW phased-array designs compared to competing solutions,” according to the company.
The chipset includes the ADMV4828 and ADMV4928 16-channel beamformers, the former operating in the 24-29.5GHz band and the latter at 37-43.5GHz; and the ADMV1128 and ADMV1139 wideband UDCs, operating in the same two bands respectively.
The company adds that, by enabling seamless operation of phased-array calibration functions online in the field, in addition to factory non-volatile memory (NVM), the chipset will allow “OEMs to move beyond the constraints of legacy NVM-only designs limited to one-time factory calibration of the beamformer, which does not address non-idealities external to the ICs and results in sub-optimal calibration results.“
