Abstract

In this letter, we present a tunable band pass filter (BPF) using a dual-mode circular waveguide cavity resonator using a single tuning element. For the proof of the concept, a 2nd order tunable BPF has been designed and developed over a tuning range from 4.92 to 6.1 GHz (21.4%). The measured bandwidth is 85 ± 10 MHz over the entire tuning range. The peak insertion loss is within 1.3 dB and return loss is better than 15 dB. The tunable filter is proposed to be used in high Q reconfigurable radio systems.

使用单个调谐元件的基于双模圆波导腔谐振器的频率可调带通滤波器

在这封信中，我们介绍了一种可调谐带通滤波器 (BPF)，该滤波器采用双模圆波导腔谐振器，使用单个调谐元件。为了验证这一概念，我们设计并开发了一个二阶可调谐 BPF，调谐范围从 4.92 GHz 到 6.1 GHz（21.4%）。在整个调谐范围内，测量带宽为 85 ± 10 MHz。峰值插入损耗在 1.3 dB 以内，回波损耗优于 15 dB。该可调滤波器拟用于高 Q 值可重构无线电系统。
