一种高抑制带通滤波器频选组件的研制

A multiuser design for high-restrain band-pass filter on frequency selected

介绍了一种低频段高抑制频选组件的设计方法和试验结果。该频选组件由多个带通滤波器、开关组件、转换开关、远控电路组成。测试结果表明在-20℃^+55℃温度范围内带通滤波器的高端阻带衰减≥84 dB;低端阻带衰减≥74 dB。

This paper gives the particular description of the design analysis and practical design for band -pass filter on frequency selected Its grouped several band -pass filter,switch group,diversion switches and control- circuit; Test result show obstruct band hign- end ≥ 84 dB;low -end ≥ 74 dB on temperature from - 20℃ - -＋ 55℃.
