Abstract

A new band-pass filter design technique is presented that uses coplanar passive interdigitated filters assisted by an MMIC active component which performs a negative resistance with an associated imaginary part in order to compensate for the losses of the passive filter and to reduce significantly the length of the resonators. A tunable version of the filter is also presented.
多标准移动通信系统中使用MMIC负阻芯片的频率可调共面滤波器结构的损耗和尺寸的改进
提出了一种新的带通滤波器设计技术,该技术采用共面无源交叉滤波器,并辅以MMIC有源元件,该有源元件具有相应的虚部负电阻,以补偿无源滤波器的损耗并显著缩短谐振器的长度。本文还介绍了该滤波器的可调版本。
