摘　　要：为适应现代机载宽频通信设备对其滤波器的严格要求,在继承了传统滤波器设计理论的基础上,设计了一种新型带通滤波器电路结构。通过适当的网络变换,使原有集中参数的椭圆函数滤波器电路网络成为能够适应高频工作并已经吸收了寄生参量的稳定结构。试验结果表明:该滤波器具有低的插损、高矩形系数、优良的电压反射系数和长时间承受连续波大功率的高性能。Based on the traditional design method of filter , a new circuit structure of LC band - pass filter is designed in order to meet the demand of modern airborne broadband communication equipment. Using proper network transformation, a stable circuit structure is obtained out of parasite parameters. Experiments show the filter has the characteristics of low insert loss, high ratio of stop - band suppression, low ratio of VSWR and enduring high power of constant wave for long time.
