摘　　要：在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一 ,而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发 ,比较了几种可用于实现带通滤波器快速变频的方案 ,选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案 ,并运用 Agilent公司的 EDA软件设计了可用于 4 0 0 MHz～ 4 50Frequency hopping is one of the most important anti jamming methods in military communications. In frequency hopping system, we can obtain better system performance, if we use a bandpass filter with the center frequency which can trace the hopping frequency quickly. This paper compares some kinds of methods for changing filter center frequency quickly and chooses a simple method which uses switching capacitor array. We also use a EDA software offered by Agilent Technology to design the filter and obtain desirable results.
