Analysis of Phased-Array Radiation Pattern Error Effect for 5G Transceiver Design

摘要

The fifth generation new radio (5G NR) is supposed to utilizemillimeter-wave frequencies for multi-Gbps data-rate. 5G NRband n260 located at 39 GHz provides 3-GHz bandwidth,which can greatly increase the data-rate compared with currentcellular network. However, due to the high free spacepath loss (FSPL) at millimeter-wave frequency, phased-arrayarchitecture is usually employed to enhance transmittedsignal strength. Thanks to the advancement of modernsemiconductor technology, millimeter-wave communicationsystems are developed and integrated monolithically inCMOS [1–4] with high reliability. This paper presents theanalysis of radiation pattern error effect for 5G millimeter-wavephased-array transceiver design.
