摘　　要：设计了一种用于跳频通信系统接收机射频前端的UHF频段电调谐滤波器。使用安捷伦公司的微波仿真软件ADS对电调谐滤波器进行结构设计和参数优化。对制成品的实际测试表明,该调谐滤波器工作频段为225~400 MHz,3 dB带宽6.5~15 MHz,通带增益24~27 dB,矩形系数小于6.2,其性能指标完全达到设计要求,在不同的频点都具有良好的电参数指标。所提方法对电调滤波器的设计具有指导作用。An ultra high frequency（UHF） band electrically tunable filter is designed for frequency-hopping（FH） communication system RF front-end. The electrically tunable filter＇s structure is designed and its parameters are optimized by Agilent＇s ADS software. The test of the product indicates that its operation band is225 -400 MHz, 3 dB band is 6.5 ~ 15 MHz, pass band gain is 24 - 27 dB, rectangle coefficient is less than 6.2. The electri- cally tunable filter meets the design requirements and it achieves excellent electrical characteristics for each fre- quency point. The proposed method is of guidance for the design of electrically tunable filters.
