Abstract

This article presents advancements and key considerations in the design implementation of phased array transceivers for the fifth-generation (5G) communication networks. It emphasizes the significance of careful consideration and system-level optimization to realize the full potential of phased array transceivers. The focus is on antenna elements and beamforming techniques with a detailed discussion on different types of beamforming techniques used in wireless communication systems. These include analog, digital, and hybrid beamforming. The article starts by introducing the concept of a phase shifter, which is a crucial component in controlling the phase of the transmitted signal. It then proceeds to discuss the role of a variable gain amplifier in amplifying the signal received by each antenna element of the array, followed by emphasizing the importance of a Low-Noise Amplifier (LNA) in transceiver design to amplify weak signals with minimal noise. In addition, this article provides a detailed discussion on the mixer, which is used to downconvert or upconvert the frequency of the received signal to a more appropriate frequency for further processing or transmission. Finally, the power amplifier (PA), which is used to boost signal power in 5G networks, is also discussed in detail.

支持下一代5G通信网络的先进相控阵收发器

本文介绍了第五代(5G)通信网络相控阵收发器设计实现的进展和关键考虑因素。它强调了仔细考虑和系统级优化对实现相控阵收发器的全部潜力的重要性。重点是天线元件和波束形成技术，并详细讨论了无线通信系统中使用的不同类型的波束形成技术。包括模拟波束形成、数字波束形成和混合波束形成。本文首先介绍了移相器的概念，移相器是控制传输信号相位的关键部件。然后讨论可变增益放大器在放大阵列的每个天线单元接收到的信号方面的作用，然后强调在收发器设计中低噪声放大器(LNA)以最小噪声放大弱信号的重要性。此外，本文还对混频器进行了详细的讨论，它用于将接收到的信号的频率下变频或上变频到更合适的频率，以便进一步处理或传输。最后，对5G网络中用于增强信号功率的功率放大器(PA)进行了详细讨论。
