摘要

本文提出了一种结构紧凑、带外性能优良的带通滤波器。阶跃阻抗谐振器(SIRs)用于实现扩展抑制带宽。此外，还引入了负载插脚来抑制谐波响应。SIRs和加载的存根占用很少的额外空间，因此所提出的滤波器具有紧凑的尺寸。本文提出了一种以2ghz为中心的带通滤波器，其20db抑制电平可达16ghz左右。

Compact cascade quadruplet bandpass filter with extend rejection bandwidth

This paper proposes a compact bandpass filter with excellent out-of-band performance. Stepped-impedance resonators (SIRs) are used to achieve an extended rejection bandwidth. Loaded stubs are also introduced to suppress the harmonic responses. The SIRs and the loaded stubs take up little extra room, and thus the proposed filter has a compact size. In this paper, a bandpass filter centered at 2 GHz is presented, with 20 dB rejection level up to about 16 GHz.
