提出了一种窄带可调谐带通滤波器的独特设计方法，其重点是设计相邻谐振器之间耦合系数的调谐中心频率依赖性。提出了新的架构，并从能量表达式导出了耦合系数的方程。搭建并测试了具有独立可调中心频率和带宽的微带原型机，并表现出优异的性能。
A unique design approach for narrowband tunable bandpass filters is presented which focuses on engineering the tuned center-frequency dependence of the coupling coefficient between adjacent resonators. New architectures are presented, and equations for the coupling coefficient are derived from energy expressions. A microstrip prototype with independently-tunable center frequency and bandwidth was built and tested, and exhibits excellent performance.
