摘要

提出了一种新型恒绝对带宽变容调谐双带滤波器。它由一对半波长开放式谐振器和一对四分之一波长短端谐振器组成。谐振器采用两种不同的方法来控制电耦合和磁耦合，从而实现恒定的绝对带宽。设计了一种双带可调谐滤波器，并对该滤波器进行了实测，结果表明了该设计方法的有效性。

Varactor-tuned dual-band filter with constant absolute bandwidth

This paper proposed a novel varactor-tuned dual-band filter with constant absolute bandwidth. It is composed of a pair of half-wavelength open-ended resonators and a pair of quarter-wavelength short-ended resonators. The resonators utilized two different methods to control the electric and magnetic coupling so as to achieve constant absolute bandwidth. A dual-band tunable filter is designed, and the measured results of the filter illustrate the effectiveness of this design method.
