摘　　要：为满足5G通信技术的多标准和多频段需求,针对如何提高多频段效率的问题,提出了一种三次谐波控制的三频功率放大器设计方法。首先基于F类功率放大器的原理设计了三频谐波控制网络,用于提高三频功率放大器效率;然后又给出了一种三频基波匹配方法,用来实现任意三频的基波匹配并简化输出匹配结构;最后设计了一款高效率的三频F类功率放大器并进行测试,测试结果表明该功率放大器在1.8、2.6和3.4 GHz的漏级效率分别为74.2%、73.8%和69.0%,饱和输出功率均在40 dBm左右,增益也可达到14.5 dB。In order to meet the multi-standard and multi-band requirements of 5G communication technology,aiming at how to improve the multi-band efficiency,a design method of three-band power amplifier controlled by third harmonic was proposed.Firstly,based on the principle of class F power amplifier,a three-frequency harmonic control network was designed to improve the efficiency of threefrequency power amplifier.Then a three-frequency fundamental wave matching method was given to realize arbitrary three-frequency fundamental wave matching and simplify the output matching structure.Finally,a high-efficiency three-band class F power amplifier was designed and tested.The test results show that the drain efficiency of the power amplifier is 74.2%,73.8%and 69.0%at 1.8,2.6 and 3.4 GHz,respectively.The saturated output power is about 40 dBm,and the gain can reach 14.5 dB.
