摘要

介绍了5G毫米波相控阵收发器的关键模块，包括宽带高效功率放大器(PA)、无幅移相器和无相变增益放大器(VGA)。在5G毫米波频段工作的这些电路的设计仍然面临挑战。为了解决这些挑战，提出了用于宽带放大器设计的弱耦合级间变压器、用于360°无幅移相器设计的三谐振负载技术和用于无相VGA设计的动态元素消除技术。它们为5G毫米波相控阵收发器前端的设计提供了可能的解决方案。

Key Circuit Building Blocks for 5G Millimeter-Wave Phased-Array Transceiver Front-End (Invited)

Key building blocks for 5G millimeter-wave (mm-Wave) phased-array transceiver including broadband high-efficiency power amplifier (PA), amplitude-invariant phase shifter and phase-invariant variable gain amplifier (VGA) are presented. Challenges remain for the design of these circuits operating at the 5G mm-Wave band. To address these challenges, techniques are proposed such as weakly-coupled inter-stage transformer for broadband PA design, triple-resonating load technique for 360° amplitude-invariant phase shifter design and dynamic elements elimination for phase-invariant VGA design. They provide possible solutions to the design of 5G mm-Wave phased-array transceiver front-end.
