Abstract:
With targets of cost reduction per bit and high energy efficiency, 5G and beyond call for innovation in the mmWave transmitter architecture and the power amplifier (PA) circuit. To illustrate these points, this paper firstly explains the benefits and design implications of the hybrid beamforming structure in terms of the mmWave spectrum characteristics, energy efficiency, data rate, communication capacity, coverage and implementation technology choices. Then after reviewing the techniques to improve the power amplifier (PA) output power and efficiency, the design considerations and test results of 60 GHz and 90 GHz mmWave PAs in bulk complementary metal oxide semiconductor (CMOS) process are shown.
