微带发夹式带通滤波器设计

内容简介：依据低通滤波器原型基本理论，进行数学建模，并利用Serenade软件设计一种X波段7阶微带发夹型带通滤波器，其中心频率为11GHz，带宽800MHz。对制作的微带电路进行实际测试，测试结果表明，该滤波器能够满足设计要求。

Abstract：Mathematical models are established according to the basic theory of lowpass filter prototype, and the microstrip hairpin bandpass filter of seventh order in the X-band is designed using the serenade software, with a central frequency of 11 GHz and bandwidth of 800 MHz. The got-up microstrip circuit is tested, and the testing re- suits show that the filter meets the demand of design.
