    摘要:

    针对宽带高效率功放的设计要求,基于宽带匹配网络设计了一款GaN宽带高效率功率放大器,其工作频率覆盖整个S波段。仿真结果显示,该功放在整个S频段内漏极效率(DE)大于62%,功率附加效率(PAE)大于57%,增益大于10.6 dB。实测结果表明,该功放在整个频段内DE大于54%,PAE大于48%,增益大于9 dB,增益平坦度在1 dB以内,实现了S波段高效率宽带功率放大器的设计。

    Abstract:

    A GaN broadband high efficiency power amplifier is designed based on the broadband matching network for the requirements of the broadband high efficiency power amplifier, covering the entire S band. Simulation results show that the Drain Efficiency(DE) is better than 62%, the Power Added Efficiency(PAE) is better than 57% and the gain is more than 10.6 dB. And the test results show that the DE is better than 54%, the PAE is better than 48% and the gain is more than 9 dB, the flatness of the gain is less than 1 dB, achieving the design of the broadband high-efficiency power amplifier.
