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-The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program
