摘要:

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11 GHz,带宽800 MHz。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。

关键词: X波段, 发夹线, 带通滤波器, 耦合系数

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 results show that the filter meets the demand of design.

Key words: X-band;hairpin;bandpass filter;coupling coefficient
