摘要

功率放大器在现代无线通信系统中起着非常重要的作用。本文设计制作了一个工作在2.11GHz-2.17GHz频段的ab类功率放大器，并对其进行了调谐和测量。测量结果表明，在1dB压缩点(P1dB)输出功率为46.5dBm，中心频率为2.14GHz时漏极效率为36.9%。使用双音信号测量的上TOI为52.98 dBm，下TOI为53.04 dBm。对仿真结果和实测结果进行了比较和分析。

Design and measurement analysis of Class AB power amplifier

Power amplifier plays a great important role in modern wireless communication system. In this paper, a class-AB power amplifier working in 2.11GHz-2.17GHz is designed and fabricated, tuned, measured. The measurement results show that the output power at 1dB compression point (P1dB) is 46.5dBm along with a drain efficiency of 36.9% at central frequency 2.14GHz. The upper TOI measured using a two-tone signal is 52.98 dBm, and the lower TOI 53.04 dBm. The results of simulation and measurement are compared and analyzed.
