摘　　要：论述了SLF通信系统中开关功率放大器谐波产生的机理,分析了目前SLF通信系统中采用LC滤波方案来抑制谐波的优点和局限性。结合SLF通信系统的实际,提出了APF和波形合成两种进一步抑制谐波的方案,并论证了其可行性。The mechanism of harmonic restraining in switching Power Amplifier of SLF communication system is dis-cussed, and the advantages and limitations of SLF ommunication system using LC filter scheme to suppress the harmonic at present are analyzed. Combined with the practical of SLF communication system, further harmonic suppression scheme with synthesis of APF and waveform is proposed, and its feasibility is proved.
