Architecture and Circuit Choices for 5G Millimeter-Wave Beamforming Transceivers.

As 5G takes advantage of the vast amount of available spectrum in the mmWave bands, system and circuit designers face new challenges to create efficient, high-performance phased array transceivers. This article covers scaled CMOS circuit and system tradeoffs for large mmWave power consumers including the PA, LO generation, and LO distribution, in the context of mobile link requirements and beamfor...
