摘　　要：利用阶跃恢复二极管的非线性特性,设计并制作了一个基于倍频的微波频率源。结合ADS软件的仿真结果,对频率源的各单元电路进行了原理分析,为其设计了一个平行耦合结构的窄带滤波器,对实际制作的频率源成品进行了测试。结果表明,该频率源的输出频率为1.5 GHz,输出功率为0 dBm,输出频谱纯净,并已成功应用于某光发射系统中。A novel microwave frequency generator based on frequency multiplication was designed and fabricated by utilizing the non-linear characteristics of step recovery diode（SRD）. Combined with the simulation results of software ADS, the operational principle for each circuit cell of the generator was analyzed, a narrow-band filter of parallel coupling structure was designed for the generator and the generator was tested. The testing results show that the output frequency of the generator is 1.5 GHz with an output power of 0 dBm and pure spectrum, which is applied into an optical transmitter successfully.
