主 题:Energy-efficient Linearization Massive multiple input multiple output(mMIMO) Monolithic microwave integrated circuit(MMIC) Power amplifier
摘 要:Highly efficient power amplifiers(PAs)and associated linearization techniques have been developed to accommodate the explosive growth in the data transmission rate and application of massive multiple input multiple output(mMIMO)*** this paper,energy-efficient integrated Doherty PA monolithic microwave integrated circuits(MMICs)and linearization techniques are reviewed for both the sub-6 GHz and millimeter-wave(mm-Wave)fifth-generation(5G)mMIMO systems;different semiconductor processes and architectures are compared and *** the 5G protocols have not yet been finalized and PA specifications for mMIMO are still under consideration,it is worth investigating novel design methods to further improve their efficiency and linearity *** predistortion techniques need to evolve to be adapted in mMIMO systems,and some creative linearity enhancement techniques are needed to simultaneously improve the compensation accuracy and reduce the power consumption.
