摘要

本文提出了一种宽谐波抑制大于4f0的带通滤波器的设计。设计采用步进阻抗谐振器结构控制中心频率，采用短段负载抑制谐波。该带通滤波器专为支持2.45 GHz的WLAN而设计。在中心频率2.44 GHz处，所设计的带通滤波器的插入损耗为1.00 dB，回波损耗为29.26 dB。谐波抑制可使插入损耗在-16 dB以下，抑制频率可达10 GHz。

Bandpass filters using stepped impedance resonators and stub loads for wide harmonics suppression

This paper proposes design of a bandpass filter with wide harmonics suppression more than 4f0. Designing uses step-impedance resonators structure for operates the center frequency and uses stub loads for harmonics suppression. This bandpass filter is designed for support WLAN at 2.45 GHz. The measured results of the proposed bandpass filter have the insertion loss 1.00 dB and the return loss 29.26 dB at the center frequency 2.44 GHz. The harmonics suppression can be suppressed the insertion loss lower than -16 dB up to 10 GHz.
