摘要

研究了有源天线相控阵发射机的非线性畸变效应。利用非线性建模技术，详细研究了功率放大器与天线之间的联合相互作用。基于28 GHz GaN MMIC PA和64元天线阵列的数值模拟用于举例说明所提出的技术在典型5G应用中的使用。结果表明，天线的相互耦合将导致各个声源的压缩特性，从而导致远场畸变显著依赖于波束转向角。

Analysis of nonlinear distortion in phased array transmitters

This paper investigates nonlinear distortion effects in active antenna phased array transmitters. Using a nonlinear modeling technique, the joint interactions between power amplifiers and antennas are investigated in detail. Numerical simulations based on a 28 GHz GaN MMIC PA and a 64-element antenna array are used to exemplify the use of the proposed technique in a typical 5G application. The results show that the antenna mutual coupling will cause the individual PA compression characteristics and hence the far field distortion to depend significantly on beam steer angle.
