摘要

本文介绍了用于n77频段(3.3-4.2 GHz)的第五代(5G)手机应用的功率放大器(PA)的设计、实现和测量。PA的功率级采用AC (alternating Current)堆叠方式，满足5G手机有限的供电电压和不断增加的输出功率要求。所实现的PA模块在5G-NR (New Radio) 100mhz信号调制条件下，在3350 MHz ~ 3900 MHz和4150 MHz频段，在3.4 V电源电压下，整个n77频段的线性增益超过31.3 dB，输出功率分别超过28.7 dBm和27.3 dBm。

AC-Stacked Power Amplifier for 5G Mobile Handset Applications in Band n77

This paper describes the design, implementation and measurement of a power amplifier (PA) for the fifth-generation (5G) mobile handset applications operating in Band n77 (3.3-4.2 GHz). The power stage of the PA applies an AC (Alter-nating Current) -stacked method to meet the requirements of the limited supply voltage and the increasing output power of 5G mobile handsets. The implemented PA module delivers the linear gain of more than 31.3 dB in the entire of Band n77 and the output power of more than 28.7 dBm and 27.3 dBm from 3350 MHz to 3900 MHz and at 4150 MHz, respectively, at a 3.4 V supply voltage under the modulation condition of a 5G-NR (New Radio) 100 MHz signal.
