摘要: 定量地分析了輸入諧波控制理論對功放效率的影響。同時,選用了南京電子器件研究所的0.25 ?滋m GaN HEMT器件,并對該GaN HEMT器件進行了負載牽引仿真和大信號仿真。根據(jù)仿真結果發(fā)現(xiàn),通過輸入諧波控制可以提升射頻功率放大器的效率,在頻帶內能獲得3~10%的效率提升。以此設計了一款X波段單級MMIC功放。經(jīng)測試,該功放芯片在9.2~11.3 GHz范圍內功率附加效率最大可以達到 52.88%。

Abstract: The influence of input harmonic control theory on the performance of power amplifier efficiency is qualitatively analyzed. At the same time, the 0.25 ?滋m GaN HEMT device from Nanjing Institute of Electronic Devices was selected, and the load pull test and harmonic balance simulation of the GaN HEMT device were carried out. According to the test results, it is found that the efficiency of the RF power amplifier can be effectively improved through the input harmonic control, and an efficiency improvement at 3~10%can be obtained in band. Based on this, an X-band single-stage monolithic microwave integrated circuit(MMIC) power amplifier was designed. After testing, the power amplifier chip has a maximum PAE at 52.88% in the range of 9.2 to 11.3 GHz.
