| 摘 要： | 本文采用桥接网络法设计了一个LC电调带通滤波器，1dB通带连续可调范围为：110～125MHz至110～155MHz、体积为25mm×13mm×7mm。对桥接网络法的椭圆类型滤波器做了深一层研究，找到了提高其矩形系数及带外抑制的改进方法。

| Abstract: | This paper designs a Lumped Component （LC） electrically tunable bandpass filter by employing a novel design method of bridge-connected network method. Its performances are tunable 1 dB band- width from 110-125 MHz to 110-155 MHz, small volume of 25 mm× 13 min× 7 mm. In addition, there is forward discussion of elliptic bandpass filter of this novel design method, resulting in an improved method of synthesizing a tunable bandpass filter with better stopband attenuation. |
