微波电路的仿真和设计

Simulation and Design of Microwave Circuit

仿真软件越来越广泛地应用于微波电路设计中。介绍了微波电路与系统仿真软件Sere-nade8.5的功能和应用,并以微波低通滤波器的仿真和设计为例说明了它的使用。以巴特沃斯原型滤波器为基础,首先分析了它的特性,然后对其进行优化,得到满足设计目标的低通滤波器。

Simulation software is applied in mi crowave circuit designing more and more widely.The function and application of Serenad e8.5that is a powerful microwave cir cuit and system simulation software are introduced in this paper.And an e xample of the simulation and design o f a microwave low pass filter(LPF)is presented to illustrate its application.The filter is based on Butterworth prototype filter.Firstly its feature is analyzed,and then it i s optimized to fulfill our desired te chnical target.
