摘要

本文提出了一种具有新型组合器的失相功率放大器。通过用带阻带抑制的串联微带线代替经典结构中的四分之一波长阻抗，该电路在保证可接受的效率和线性度的同时实现了宽带宽。通过分析和ADS仿真，实现了中心频率为3.1GHz、带宽为200MHz的分相放大器。模拟结果在所有考虑的情况下都显示出良好的一致性。

Improved Combiner Design for Broadband Outphasing Power Amplifier

In this paper, an outphasing power amplifier(PA) with novel combiner is proposed. By replacing quarter wavelength impedance in classic structure with series microstrip lines with stop-band suppression, the proposed circuit achieved wide bandwidth while ensuring acceptable efficiency and linearity. Analytical and ADS simulation are presented in this work, an outphasing PA operating at center frequency 3.1GHz with 200MHz bandwidth is realized. The simulated results show excellent agreement in all cases considered.
