摘　　要：介绍了集总参数LC微波多工器的设计原理和MicrowaveOffice在微波多工器设计中的应用。从工程实践的角度提供了一种易调试、低成本LC微波多工器的设计模型,该模型主要采用高通滤波器和低通滤波器相互组合来实现有用信号的合并与分离,使设计简单易调,适合于批量生产。给出了集总参数微波多工器软件设计的仿真效果和设计模块的测试结果。从测试结果可以看出,主要通道的相对群时延特性和回波损耗特性与仿真结果符合较好。The fundamental of designing lumped constant microwave multiplexer and the application of MicrowaveOffice in the design of microwave multiplexer is introduced. From the engineering angle, a kind of design model about easily-tuned and low cost LC microwave multiplexer is given. In order to tune the module easily and fit to batch production, in this model, the combination of high-pass filter and low- pass filter is adopted to implement the incorporation and separation of the useful signal. At last, the emulation result of lumped constant microwave multiplexer and the measured result of this model are given. From the measured result of this model, the comparatively perfect characteristics of relative group time delay and return loss are shown.
